Compression Of Aerial Image Data Using Adaptive Discrete Cosine Transform (ADCT)

The amount of data associated with visual information is so large that its storage would require enormous capacity. Although the capacities of several storage media. In order to reduce the volume of pictorial data which one may need to store or transmit, the research modifies a method for image data compression based on the new algorithm to optimize the compression performance by DCT classification scheme for the image blocks is adopted, a bit allocation matrices them, designed to assign a given number of bits for each retained transformed coefficients.
