Program Plan Intro
Gouraud shading and Phong shading:
Shading is the process of implementing illumination model at the pixel points or on the surface of the polygon of graphic objects. There are two main types of shading process implemented in the process. These are Gouraud shading and Phong shading. Gourand shading is the process of color computation based on per-vertex while Phong shading is the process of color computation based on per-fragment.

In terms of the perspective projection camera model, two things occur simultaneously during a dolly zoom sequence: the camera moves along the z-axis, and the focal distance of the camera changes. The distance moved and the change of focal length are carefully chosen so that the projection of objects at a predefined distance remain at the same image position. Objects at all other distances move relative to one another. A photographer wants to capture two images of a scene captured at either end of a dolly zoom, such that the image positions of points in the world at a distance of α cm relative to the camera that took the first image remain the same. The first image is captured with a focal length of β cm. To capture the second image, the camera was moved γ cm along the z-axis in the negative direction. What focal length should be used to capture the second image to successfully perform the dolly zoom.

- When rasterizing two triangles that lie on different sides of a common edge, there should be neither multiple fragments for a pixel nor holes between the two triangles. Describe how these requirements can generally be implemented in rasterization! Why is it important that the decision whether a pixel belongs to a triangle can always be made locally based on the data of each individual triangle?arrow_forwardFor an object detection problem, assume you are designing a YOLO like model to do the job. Your input image size is 127x127 (RGB). We are looking for a 3x3 output grid size. The number of classes is 20 and for each cell in the grid, we are considering 2 anchors. Design the CNN network and as a designer feel free to set your network's hyper-parameters as you wish. The output of your network needs to show the final height, width, and the channel. You do not need to include post-processing (nan-max suppression) step for YOLO. In Python-arrow_forwardAssume that I is a grayscale image, I1 is obtained by applying histogram equalization on I, and I2 is obtained by applying histogram equalization on I1.

Answer the following: (a) Use the projective transformation x' = x + y + z y' = x − y + z z' = x + y − z to find the images of the images of the points (0,0,1),(1,0,0),(1,0,1) and (2,0,5).

Given a RGB color image ‘test.jpg’ noised by salt and pepper noise, first choose a good filter to remove noise on each channel, then based on the gray image of this new RGB color image, use canny edge detection to get edges.

Each image-processing function that modifies its image argument has the same loop pattern for traversing the image. The only thing that varies is the code used to change each pixel within the loop. Design a single function, named transform, which expects an image and a function as arguments. When this function is called, it should be passed by another function that expects a tuple of integers and returns a tuple of integers. This is the function that transforms the information for an individual pixel (such as converting it to black and white or gray-scale) The transform function contains the loop logic for traversing its image argument. In the body of the loop, the transform function accesses the pixel at the current position, passes it as an argument to the other function, and resets the pixel in the image to the function’s value. Write and test a script that defines this function and uses it to perform at…arrow_forward
- A robot starts on a point marked “A” on a rectangular grid of points. The starting point is always the top left point on the grid. The robot can move left, right, up or down, moving from one point to the next. By moving in steps going left, right, up or down, the robot would like to reach a point marked “B”, which is always the bottom right point in the grid. Sometimes, points are marked as “x”, and the robot is not allowed to visit them at all. A robot is never allowed to visit a point more than once. In how many ways can the robot move from A to B and visit all points along the way? For example, in the following grid, represented in text as A . . . . B there is only one path from A to B: In the following grid, represented in text as A . . x x B there is still only one path (we're lucky because of the two x's): However, in the grid A . . . x B there are no ways for the robot to move from A to B and visit all points that are not marked with “x”.
