摘要：
In this paper we show the obtained results when using the Discrete Cosine Transform (DCT) into the compression and decompression of digital images; for which, the image is divided in square blocks of nxn. Later these blocks are quantized and codified with the Huffman encoding technique. The computational process is made by means of the Fast Discrete Cosine Transform algorithm (FDCT) [1] programmed in C language. The analyzed images are directly caught by means of a camera and they are sent to a personal computer through a developed video digitizer hardware.
