An acronym for Portable Network Graphics, PNG is a lossless file format designed as a more open alternative to the Graphics Interchange Format (GIF). Unlike JPEG, which relies on DCT compression, PNG usesLZW compression, which is the same as GIF and TIFF formats. Boiled down, PNG’s two-s...

A task of alternative (faster and more efficient in compression ratio sense) coding of discrete cosine transform (DCT) coefficients within JPEG based image compression approach is considered. In the data processing chain, it is proposed to apply a recursive group coding (RGC) as an alternative ...
【摘要】Focusing on the problem that the JPEG image compression algorithm widely used in the Android platform has high distortion rate,the JPEG2000 image compression algorithm was proposed as a new compression alternative algorithm.The Peak Signal-to-Noise Ratio (PSNR) value,Mean Structural SIMilarity...
One alternative to shooting, editing and compressing your own images is using stock images, but theproblem with stock photographyis that it can hurt your brand if misused. Learn the bestways to use stock photosfor your business to ensure success. ...
What is an alternative to JPEG files?A good alternative to JPEG files is the PNG format. PNG files are lossless files which means that after compression, it doesn’t lose any data, unlike JPGs. PNG files offer better text readability, making them the better choice for infographics, ads, ...
If you don’t want to perform JPEG lossy compression on your site’s images, there’s always the alternative: lossless compression. Lossless compression saves your images in an entirely different format (usually PNG). While the image quality is never sacrificed because no information is eliminated...
With heavy compression, files are virtually indistinguishable from the original viewed at 100%. It’s not until you zoom in at 200, 300%+ where artifacting becomes visible. Great option for those looking for an affordable alternative. more ...
That leaves only Option 1 as an alternative, and I don't like that option as much as what we're already doing. What we're already doing is consistent, since it extends each of the data-precision-specific functions to handle data precisions less than the maximum data precision supported ...
Due to exponential growth in image sizes, visually lossless coding is increasingly being considered as an alternative to numerically lossless coding, which... O Han,A Bilgin,MW Marcellin - 《IEEE Transactions on Image Processing A Publication of the IEEE Signal Processing Society》 被引量: 49发表...
