Lossy image compression retains the most significant information for the image without keeping every single pixel. There are several types of lossy compression algorithms, described in more detail below. But all work by removing information from the image file so that the file is comprised of fewer...

An image compression and expansion apparatus reproduces an expanded image corresponding to an original image from a reduced image. The original image data is comprised of approximately 1000×600 pixel values Pyx. A first matrix Mcomprised of 64×64 pixel values Pyx is extracted from the original ...
Image Compression Compression reduces image detail and size by removing some of its header information. The favored file formats for raster imagecompressionare .png, .jpg, and .gif—each containing static pixel color data. Each lets you adjust the quality, level of detail and size when saving e...
Our compression networks are comprised of an encoding network E, a binarizer B and a decoding network D, where D and E contain recurrent network components. The input images are first encoded, and then transformed into binary codes that can be stored or transmitted to the decoder. The ...
Instead of modifying the original image formation process, our approach builds on the neural network framework proposed in the blind compression work1, which allows the key front-end image processing task to be accomplished using a single matrix-vector multiplication. Fortunately, analog optical computi...
Image compression and decompression techniques are described. A user may employ a wide variety of devices to view images. However, the capabilities of these devices may differ greatly. For example, a traditional image format that may be readily processed by a feature-rich device (i.e., a “...
Graphic images are generally considered to be those images comprised of text and/or drawings. Data compression of graphics images is desired whenever a fast image transmission speed is desired in a limited band width channel. It is also used for storage of a large number of images in a limite...
Information distortion in regions of image edge is more perceptible for people than those in other regions. To improve the performance on the edge, we present an improved embedded zero-tree wavelet image compression algorithm with weighted sub-block-trees and adaptive coding order. First, we assign...
