A Novel Compression Technique for JPEG Error Analysis and for Digital Image ApplicationsCh Chandra Sekhar
The file format which employs this compression is commonly also called JPEG; the most common file extension for this format is .jpg, though .jpeg, .jpe, .jfif and .jif are also used. JPEG itself specifies both the codec defining how an image is transformed into a stream of bytes, and ...
This paper proposes a JPEG image compression technique based on all phase inverse discrete cosine biorthogonal transform(APIDCBT).The APIDCBT matrix is a new form of transform matrix.This paper demonstrates its expression and proposes the definitions of biorthogonal transform and dual biorthogonal base...
Digital color images are compressed using common standards such as JPEG. The compression technique is used in various applications such as imaging and equalization of channels. But the decompression technique is not having enough sources to handle various problems. The process of sampling and sub samp...
JPEG (pronounced "jay-peg") is a standardized compression method for full-color and gray-scale images. This software implements JPEG baseline, extended-sequential, and progressive compression processes. Provision is made for supporting all variants of these processes, although some uncommon parameter ...
aJPG, also known as JPEG, is a file format that can contain image with 10:1 to 20:1 lossy image compression technique. With the compression technique it can reduce the image size without losing the image quality. So it is widely used in web publishing to reduce the image size maintaining...
) differences than it is to Cb (chroma relative blueness) and Cr (chroma relative redness) differences, these latter two components can be subsampled by only storing a single value for each, in every 2×2 pixel matrix. JPEG allows other matrix sizes, but 2×2 is the most common....
Jpegli is a new technique for encoding and decoding traditional JPEGs. TheJpegli coding libraryis fully compliant with 8-bit JPEG, meaning that a Jpegli-encoded image can be opened in any old browser, photo editor, or photo viewer. To reiterate, this is a JPEG encoding method, not a ne...

over the internet. This can greatly reduce the size of documents and other sparse files that have a large amount of redundant data. Photographs are, on the other hand, typically densely packed with unique information that is difficult to break into repeating components for lossless compression. ...
