Designing A New Low Complexity Approximation For Image Compression

Pixel count - A pixel is a physical point in an image represented on the screen. The intensity of each pixel is variable. The more pixels, the better the quality. Resolution

Digital graphics are in their own way an art form, digitally constructed to create phenomenal images. However, you need to have some sort of artistic ability combined with a suitable computer system before you can design the perfect graphic.

Electromagnetic waves are continually used to upgrade and advance our technology, being implicated for its use in microwave ovens, radio waves for telecommunications and x-rays in medicine.

Ultrasound waves, which are pictures or imaging that can be used for industrial, navigational, and security applications. Also used in medicine to view internal organs of people's bodies. They use the echo between object to show a picture or video of the internal organs, so the distance to an object can be determined by measuring the delay between the sound of an ultrasound pulse

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, though pretty much the industry standard at this point, is still a young technology. Many of the greatest advances in digital happened within the last ten years, and if you're a later adopter it's nothing to be ashamed of - there are millions of people out there that have never touched a digital camera.

For instance, the speed of light has been measured at roughly 670 million miles per hour (Wile 365). With some math, scientists have learned that light can travel the circumference of earth approximately 7 times each second and that it takes around 8 minutes for the sun’s rays to reach earth. Scientists can now calculate the wavelength, which is the distance between two crests, and frequency of a light wave, but also the energy of a photon at the same time and use the values interchangeably (Wile pp. 352 and 373). The electromagnetic spectrum, the collection of all forms of light, shows that visible light is only a small fraction of all light. The spectrum ranges from energetic gamma, X-ray, and ultraviolet radiation to relatively low-energy light waves such as infrared, microwave, radar, TV, and FM and AM radio. Visible light, also known as the visible spectrum, sits between ultraviolet and infrared. It is the only portion of the electromagnetic spectrum that humans can see (Wile 370). Although much of the spectrum is unperceivable to the eye, it has numerous uses. For example, X-rays are used to find broken bones and treat cancer, infrared light is used in remote controls, microwaves heat food, and FM and AM waves are used in

Computer art usually refers to any form of graphic art or digital imagery that was created with the aid of a computer. Computer art which curators today call digital art or new media art started to emerge in the 1950 and focused mainly on geometric shapes in random combinations. Many critics at the time questioned whether computer art could in fact be called art. Critics wondered whether computer art could still convey concepts of “meaning”, “expression”, and “form”.

Cameras are involved with physics because they use visible light to capture a picture. Visible light is part of the electromagnetic spectrum. The electromagnetic spectrum contains different wavelengths and frequencies. The visible light spectrum is the part of the electromagnetic spectrum that humans can see. Specific wavelengths in the spectrum are represented by specific colors. This is how humans are able to perceive colors, through visible light. When a camera captures an image, it uses visible light to capture the different wavelengths. These wavelengths are seen as different colors which come together to create the image. Visible light is what allows the colors that create the image to be seen when the picture is captured.

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

Adding on from this report, I will compare the limitations of hardware/software where I will select two graphic-related hardware devices and compare their limitations - the limitations of raster will also be compared. With the final point adding, I will

Increase in resolution of image has been one driving factor in the development and progress of the fields related to the capture, processing and display of digital images and video. Number of authors has carried out research on various techniques on super-resolution algorithms which are classified into two basic categories: ‘single-frame super resolution’ and the more common ‘multi-frame super resolution’. Single frame super-resolution is a very ill-posed problem due to the lack of any new additional information. Multi-frame Super resolution on the other hand presents more information in the form of Low Resolution (LR) frames that are displaced from each other making it a more tractable problem. A related problem to super Resolution (SR) techniques is image restoration, which is well established area in image processing application. An other problem related to SR reconstruction is image interpolation that has been used to increase the size of a single image.

After all the pre-processing activities, one of the actual work of the study is image classification which is the basis for change detection activity. Classification is one of the seven change detection mechanisms and supervised classification was employed for this study. Supervised classification requires the selection of training areas to get accurate classification output. It is profoundly based on the quality and quantity of training samples to produce good quality classification results.
