2. Lossy compression - Wikipedia

   en.wikipedia.org/wiki/Lossy_compression

   Lossy compression. In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content.

   Website. jpegmini .com. JPEGmini is a photo compression tool developed by Beamr Imaging Ltd released in 2012 for Mac and Windows. It designed to reduce the file size of images and videos with limited quality reduction. [1] [2] [3]

4. Lossless compression - Wikipedia

   en.wikipedia.org/wiki/Lossless_compression

   Lossless compression. Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [ 1] By contrast, lossy compression permits reconstruction only ...

5. Data compression - Wikipedia

   en.wikipedia.org/wiki/Data_compression

   Data compression aims to reduce the size of data files, enhancing storage efficiency and speeding up data transmission. K-means clustering, an unsupervised machine learning algorithm, is employed to partition a dataset into a specified number of clusters, k, each represented by the centroid of its points. This process condenses extensive ...

6. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats . The compression may employ lossy data compression, so that quality-measurement issues become important.

7. Video file format - Wikipedia

   en.wikipedia.org/wiki/Video_file_format

   Video file format. A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g ...
