About this document
JPEG Compression Overview Diagram by Tanveer Ahmed Hakro is a document available to read on EtoBox.
The document discusses JPEG image compression. It describes how JPEG compression works by applying the discrete cosine transform (DCT) to 8x8 pixel blocks, quantizing the resulting coefficients, and then entropy encoding the quantized values. The DCT converts pixels from the spatial domain to the frequency domain. Quantization then discards less important visual information by reducing precision of the DCT coefficients. Finally, entropy encoding such as Huffman coding compresses the data size.
