In this project, it is challenging issue to track multi-target as camera motion is unknown. To deal with this issue and targets occlusion, the camera parameters are calculated and targets were also tracked within the 3D coordinates [W. Choi] at the same time. To be specific, it is aimed 1) to solve the multi-object tracking issue by using a single non-calibrated camera, [W. Choi] 2). to deal with complicated scenes in which multiple pedestrians are moving and occluding each other [W. Choi] at the same time, 3). to calculate the 2D/3D trajectories within the camera reference system [W. Choi].
The important task in this project was to calculate camera parameters (such as camera pose and focal length of a camera) and track objects such as pedestrians as they move in the scene [W. Choi]. Tracks are helpful in calculating the parameters of a camera by using their velocity and scale within the image plane; simultaneously, camera parameters can help to follow objects very robustly as previous important information is available. This enables to calculate object 3D trajectories in the reference system of a camera. The author used a simplified camera model which allows finding a powerful compact relationship between the variables such as camera parameters and target, with the help of projection constraints of a camera. The identification of a handful of feature tracks which associated with the static background allows adding extra constraints to the camera
the incessant brutality of racism in the 1920s. Rolf de Heer’s 2002 art house feature film The Tracker, represents one of the most “unspeakable aspects of Australian history” (Smaill, 2002, 31), explicitly depicting the extreme racism, violence and inhumanity the egotistical European invaders inflicted on Aboriginals, whilst at the same time glorifies and treasures aboriginal culture and intelligence through film.
The different perspectives create interest and draw us into the experiences of others. The two texts, ‘The Tracker’ composed by Rolf De Heer and ‘Bran Nue Dae’ composed by Rachel Perkins explores this notion. Both films are evident to the racial discrimination of Aborigines in Australia. ‘The Tracker’ is a 2002 art house film set in 1922. It is clear that there were no Aboriginal rights and which white settlement had the greatest control. ‘Bran Nue Dae’ is a 2009 musical/comedy/drama film set in 1969 about the beginning of Aboriginal rights.The different perspectives are from Colonial/Indigenous people. The voices were through the role of the characters, the genre, the music and the cinematography.
Activity 1 presents the challenge of detecting vehicles in front of a stereo camera and determining the distance to them using stereo data. The team accomplished this by creating a disparity map from the two rectified images and then plotting a point cloud based on this data. A cascaded object detector is then used to get regions of interest (ROIs) where vehicles are in frame. These ROIs are then used to extract the depth of the vehicle in the point cloud. The result is a distance to the identified vehicle.
The effort for this report is guided for occlusion, tracking mechanism, camera shift and spacio-temporal. All these techniques can be implemented for different usages.
The practice of grouping students based on ability limits the likelihood for the totality of the populace to ultimately achieve an equitable education. The longevity of this practice only leads to the creation of gaps in the quality of education delivered to students from racial minority and low-socioeconomic backgrounds (Tyson, 2013). Furthermore, Black males seem to bear the brunt of ability tracking in that they often are tracked, put into special education, and have educators who are ill equipped to educate them, which paints a dismal picture for their future success (Palmer, 2010). The phenomenon of being tracked continuously omits Black males from becoming full and active participants in the globalized community.
The sniper spotter team is drop in heavily guard territory and is forced to find their way back to their company as a test. The team will be put through some hard places to provide themselves. If they don’t do t they will be put back on the training course or get disorderly. The team will have to be put in some of the hardest places on the earth to provide themselves. So they better have everything they need to survive their test.
Daniel Wilson’s Robopocalypse recounts the tale of humanities perseverance when faced with a robot uprising, as told through varied vantages. Ultimately culminating with his presence, Cormac Wallace transcribes the recordings held on a black box, which was discovered after arduous efforts by him and his band of survivors. Independently, these stories offer glimpses of humanities resistance to an end, however as a whole they paint a picture of conceited efforts coming together to serve a common goal. Wilson employs a common enemy as a means to argue that success cannot be achieved without the assistance of others.
Starting at around ten minutes in and lasting around six minutes long is the tracking shot for the movie Serenity. The shot introduces the characters and gives a look at the ship. The tracking shot helps to set the tone for how the main characters are going to interact with each other. The tracking shot starts with the introduction of two crew members of the ship, Wash and Mal.
The camera is moving many times as the three people who seem to be the focus of the scene are moving. However, the real point of the shot lies with the boy in the background which is never not in the shot.
A new cut maintains the descending vectors. We return to our original tracking shot: the camera dollies alongside the mother running down the crowded stairs. The rushing camera dolly gives us a sense of urgency. The panic overwhelms her awareness. She doesn’t realize her son is gone.
A cinematic technique that Polanski used to portray survival in The Pianist, is the use of the tracking shot. A camera technique where the camera moves alongside the object it is recording, in this scene it is Szpilman. This technique is used in multiple scenarios, specifically during a scene when Szpilman was separated from his family. Throughout the entire scene the camera was focusing on the movement and actions that Szpilman took to get away from the scenario. The tracking shot technique is used during the scene to capture Szpilman’s emotions. The emotions that the audience captured were full of sadness, fear, and mostly confusion. Szpilman had no idea what was happening whether he should go with his family or save himself. All that Szpilman knows is that his family is gone and that he needs to survive. Polanski was able to capture Jews that were abused or killed and their belongings all scattered on the ground throughout the tracking shot was in motion. Polanski used this camera technique effectively by showing great amounts of emotion and background actions.
The camera tracks backwards as Szpilman walks towards us. It gives the audience the feeling that he is limping into our hands as if we are helping a poor elderly man. Then the camera tracks from right to left as we get the impression that he is searching for something. The director chooses to track his movements slowly to make the audience feel as if Szpilman is moving along in a fragile house just like himself. The camera tracks along showing the audience a full view of him showing us the little steps he is taking just to get to the other room. There is very low lighting in this scene which shows as if he is looking for something quietly without making noise. Szpilman then finds something on the floor, so he bends down and this is shown by tilting the camera down to a low angle. The director has chosen to do it this way because it makes it flow with Szpilman’s movements. Then the camera tracks and zooms into Szpilman walking into the next room. When Szpilman finds a tin opener and uses it the camera focuses on it even though it is a small object and not important. As Szpilman carries on trying to open it the camera is still focused on it. The director makes the audience focus on that repetitive movement of trying to open it but at the same time distracting them from the characters emotions if anything surprising happens.
The audience could tell that the whole family was worried because every character in the room was focused on at one point. This scene exists to make the audience feel like they should be worried in this scene. The focus gives the audience perspective, making the audience know what they are thinking with their expressions and it can also be used to see through their eyes. You can see through their eyes by looking at the main character and then focus the camera on an object that the character is looking at. Another great scene that is great with perspective is the movie Children of Men by Alfonso Cuaròn in 2006. In this scene it is a scene with a long shot that take about some one minute. In this scene they make the camera follow our protagonist around shaking and moving. I believe that this is done because it makes the audience feel like they are the character following the protagonist around. This gives the audience more emotional attachment to this scene because I think they normally would feel like they are there. In this scene the camera is constantly looking at
Using the precise transformation matrix, any 3D data can be accurately overlaid over the video frame. Additionally, any pixel on the video frame can be translated back to latitude, longitude, and elevation using the transformation matrix and the synthetic 3D environment.
War Horse’s camera movement shows its largest change during the beginning of the war. The focus shifts from the peaceful grounds of Devon to the front line and battlefields of the raging war, the cameras function is now to capture the action in a dramatic and intense way. The brutality of the war is shown through camera movement which is contrasting to Pulp Fiction. The war scenes, an example being the “No man’s land” scene, are often filmed via a tracking or dolly shot which varies in ‘both momentum and direction in order to create and generate diverse effects’, as supported by Dix (2008, 28). The use of a tracking shot reoccurs throughout War Horse and creates realistic and believable scenes. A tracking shot makes the spectators feel that
