Description: Block compression is a method of image data compression that involves dividing the image into smaller sections, known as blocks, and applying compression algorithms to each of them independently. This approach allows for significant file size reduction without perceptible visual quality loss. Block compression is particularly effective in images with homogeneous areas, where color and texture patterns are similar. By working with blocks, algorithms can identify redundancies and apply compression techniques, such as run-length encoding or discrete cosine transform (DCT), which are fundamental in various image formats like JPEG. This method not only optimizes image storage but also improves transmission speed over networks, as blocks can be processed and sent more efficiently. Block compression is an essential component of modern graphics computing, enabling the handling of large volumes of visual data and facilitating its use in applications that require high image quality and performance, such as video games, graphic design, and online video streaming.
