An 8×8 block of DCT is compressed using quantization. A remarkable feature of JPEG Process is : the varying levels of image compression and quality is obtainable by using different quantization matrix ...

Lossless data-compression programs search through documents for redundant or repetitive data and then encode it. For example, a text document may contain 200 empty spaces, 100 instances of the ...

Image compression by singular value decomposition of the image matrix - mutaphore/svd-image-compression. Skip to content. Navigation Menu Toggle navigation. Sign in ... it is also an expensive form of ...

The canonical face recognition algorithm Eigenface and Fisherface are both based on one dimensional vector representation. However, with the high feature dimensions and the small training data, face ...

There are two types of compression algorithms, namely, loss-less and lossy-image compression. This article proposes a technique to compress the captured image to reduce its size while maintaining its ...

Recent studies have made significant strides in addressing the computational complexity of fractal image compression while simultaneously enhancing the quality of decoded images. For example, a ...

To minimize the size of the image data, video compression techniques are used. Thanks to the development work of the Fraunhofer HHI, this now happens ... The Fraunhofer HHI, for example, has made a ...
