Ahmed N, Natarajan T and Rao K R have explained basics of Discrete Cosine Transforms, and its use in image compression [4]. The JPEG2000 Standard basics and algorithms are explained by Karen L. Gray [5]. The basics and implementation of Wavelet Transform Coding is explained in detail by ...
Image compression is one of the easiest ways to improve your site's SEO as it makes your website load faster. Learn how to do that in today's article.
However, the technique of the present invention is not limited to JPEG, but may be extended to compression algorithms that use other linear-transform-based basis functions including the discrete sine transform, the discrete hadamard transform and wavelet transforms. We begin by providing a brief ...
Available as a free trial, the regularly priced $99 JPEGmini Pro is a simpleLightroom pluginor Photoshop CC extension that applies its algorithms on photo export to remove redundant binary data from your images. Explained simply: think of how the MP3 file type compresses file size by removing...
Karl M. Marks, (“A JBIG-ABIC compression engine for digital document processing,” IBM Journal of Research and Development, Vol 42, No. 6 pp. 753-758 (November 1998)) describes a chip that can encode or decode the bi-level image compression algorithms JBIG and ABIC. Thus conversion ...
The proposed algorithm is implemented within the framework of JPEG 2000, which is an international image compression standard. Despite the powerful scalability features of JPEG 2000, previous visually lossless algorithms using JPEG 2000 are optimized for only one resolution [19–21]. This implies that...

Video Optimization, Part 1: Cloudinary and the HTML5 Video Player Short-form videos—hero banners, product pages, ads, social content—are popping up on the web in places never seen before. This trend could become challenging because of the many formats and codecs, let alone inadequate experti...
(3D) compression were analyzed with the appropriate software. The compression algorithms used were the same as those used within the simulator as well as Kakadu [18] to perform 3D JPEG 2000 compression (i.e., a decorrelation method was applied not only in the spatial domain but also in the...
JPEG images do not handle upscaling very well and often produce compression artifacts.
