In this paper, we have proposed a new algorithm of the image compression using ...
Lossy compression is typically used when a file can afford to lose some data and/or if storage space needs to be drastically ‘freed up’. Here, an algorithm scans image files and reduces their size by discarding information considered less important or undetectable to the human eye. Using lo...
JPEG 2000 (JP2) is the newest version of JPEG. It slightly improves image compression performance over JPEG using two different wavelet transforms. Users can choose low to high levels of compression. LZ77 Compression LZ77 compression is a lossless image compression meaning it maintains raster values ...
advanced quantization algorithm with support for gamma correction and premultiplied alpha unique dithering algorithm that does not add unnecessary noise to the image Configurable quality level automatically finds required number of colors and can skip images which can't be converted with the desired qualit...
An algorithm for lossy compression of vector data (vector maps, vector graphics, contours of shapes) was developed. The algorithm is based on optimal polygonal approximation for error measure L2 and d 关键词: polygonal approximation quantization vector data compression vector data reduction vector map...
As the diversity of the way to obtain information ,The explosion of the big data, data storage to bring the high cost, in order to save storage resources, this paper proposes a geometric center extraction and compression algorithm based on Euclidean distance. The algorithm through the ge...

It is based on a block decomposition mechanism combined with well-known discrete cosine...
Under the hood, SPERR uses wavelet transforms,SPECKcoding, and a custom outlier coding algorithm in its compression pipeline. This combination gives SPERR flexibility to compress targetting different quality controls, namely 1) bit-per-pixel (BPP), 2) peak signal-to-noise ratio (PSNR), and 3...
They do so thanks to an efficient compression algorithm that decodes the data included in an uncompressed file and makes it smaller without audible differences. If you’re into digital hi-fi, you’ll typically be listening to lossless compressed files | Image: Naim ...
