Optical And Analog Image Processing

Digital Photography has become one of the most simplified and effective way of capturing and using the images. Digital images are very high in quality and also with the ease of viewing, editing and transferring it to any computers or mobile devices making it a very cost effective way of managing the images (Kornhaber, Betihavas, & Baber, 2015).

Another step in pre-processing is to make the image width and height divisible by 8. Let w and h represent the width and height of the image respectively. w and h are converted into w* and h* such that 8|w* and 8|h* are as follows in (1) and (2):

Digital Camera: Images play an important role in the graphic images. It is like if there are no images then there cannot be any graphics. So to edit any graphic image you will need to have an image and to get image you need to have a digital camera which will let you capture anything you want so you can use that image to edit. There are variety of cameras available in the market from very cheap to very expensive but both of them does the same work. However, the cheaper one will not have enough clearer picture or the resolution so you can choose to buy a camera with a good megapixel and resolution which will make your work easier as you will get good images.

In radiography, picture archiving and communication system enables the capture, storage, retrieval and sending of digital

Photography has come into existence due to the evolution of the renaissance craft, which often involved the artistic creation, and documentation of occasions, figures, and memories. Photography as a practice that consists of so many different styles and techniques that vary in regard to the school of photography being used. For example the Pictorialist thinks of photography as a type of fine art and therefore try to make it artistic by using pictures or visual images, which furthermore establishes their point that photography is an art or a form of fine art, on the other hand the Modernist has adapted to the modern techniques which has more focus on the sharp center of the image and using the camera as an instrument rather than seeing it as a canvass which is usually how pictorialists see it, and they also believe in creating very high quality images which

The ability to analyze and depict the elements that are portrayed in an image is a skill that is practical to own. In your educational career, throughout most subjects you are given hundreds of images to look at. Some are simple and straightforward, and others have a much more deeper meaning to what is really going on. Having the skill to analyze an image and depict all the elements gives you a clearer and broader sense of what is going on. For example the image I have chosen to analyze is of a young jewish girl by the name of Anne Frank who wrote a diary about hiding with her family in Amsterdam during World War II.

Our bodies are an amazing machine that interpret the world we live in using different processing systems. The visual information process is a system used to perceive our environment and send this information to our brain, the processing center of the body. One of the most important and often the initial sense used in perceiving our environment is vision. Vision may be the leading prominent sense we use in perception.

Shape: Shape is the way objects are both identified and connected to other objects. In individual photos, but there is a fine line between too many or not enough

A visual image is determined by the viewer, and this concept of user opinion is difficult to challenge. Rose continues by explaining that there are multiple sites in which the meaning of an image is made, beginning with “the site of the production of an image, the site of the image itself, and the sites where it is seen by various audiences” (Rose, 2016:16), which are followed by a set of modalities. Such modalities include; technological, compositional and social. The technological aspect refers to a visual technology as “any form of apparatus designed either to be looked at or to enhance natural vision” (Rose, 2016:17), this ultimately means the evolution of visual images from early paintings to television to the modern era of the internet. Compositional refers to the process of an image being made, such as the “spatial organization” (Rose, 2016:17), the actual content of the image and lastly the colour. The last modality explained by Rose is the social aspect, which refers to “the range of economic, social and political relations” (Rose, 2016: 17), meaning the socially constructed practices that interpret the image at face value (use and or visual). Photography is a technology that has been described as a medium of recording the world in a realistic way. There are technological effects that contribute to the construction of an image, some methods of looking at a visual image can be deemed unnecessary to be considered technologically produced, as images must be carefully analyzed. Rose writes, “the social to the production of images depend on rather more detailed analyses of particular industries which produce visual images” (Rose, 2016:21), which further explains the importance of taking into account all aspects of an image. Rose draws on the importance of an image by writing, “every image has a number of formal components” (Rose,

Digital photography was the reason for the graphics editing software such as Adobe Photoshop were developed, and has changed the way people take pictures. The digital camera has been in development since George Smith and Willard Boyle invented the charged-coupled device (CCD) which is an image sensor. The original intended function of the CCD was to be the new semi-conductor memory for computers. By 1975 image quality improved greatly and was able to be broadcasted over television. Since then cameras have improved eminently through the years, progressively advancing and functioning more dynamically. A digital image is a long string of 1s and 0s that represent all the pixels in an image. Just as with film cameras, the image that is recorded is visible light or flash. When the light bounces off the subject and is captured in the camera, it breaks into light patterns and is converted into a series of pixel values. The light is then converted into electric charges which are then used by the CCD or CMOS (Complementary Metal Oxide Semiconductor) to record images.

For the fast and cost effective production of patient diagnosis, various image processing techniques or software has been developed to get desired information from medical images. Acute Lymphoblastic Leukemia (ALL) is a type of leukemia which is more common in children. The term ‘Acute‘means that leukemia can progress quickly and if not treated may lead to fatal death within few months. Due to its non specific nature of the symptoms and signs of ALL leads wrong diagnosis. Even hematologist finds it difficult to classify the leukemia cells, there manual classification of blood cells is not only time consuming but also inaccurate. Therefore, early identification of leukemia yields in providing the appropriate treatment to the patient. As a solution

High-level feature extraction concerns finding shapes in computer images. To be able to recognize faces automatically, for example, one approach is to extract the component features. This requires extraction of, say, the eyes, the ears and the nose, which are the major facial features. To find them, we can use their shape: the white part of the eyes is ellipsoidal; the mouth can appear as two lines, as do the eyebrows. Shape extraction implies finding their position, their orientation and their size. This feature extraction process can be viewed as similar to the way in which we perceive the world: many books for babies describe basic geometric shapes such as triangles, circles and squares. More complex pictures can be decomposed into a structure

Photographs are created from light rays bouncing off objects. When a person looks through the viewfinder, the image they see are light rays reflected from a penta-prism, a specially shaped piece of glass inside the camera. The rays from the penta-prism came from a mirror, which reflected the rays it received from the lenses. Lenses are used to focus in or out on objects. They attain the rays from the object reflecting the rays toward the camera. For an image to be “captured” on a film camera, the button used to take

In the last decade computer technology has been introduced to photography yet again challenging the meaning
