Interframe compression using adaptive discrete cosine transform (ADCT)‎

الملخص EN

Image and video image compression techniques are paramount in the development of digital image and video systems.

It is essential to develop compression methods which can both produce high compression ratios and preserve reconstructed quality in order for the creation of high quality, affordable image and video products.

In this research was produce 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.

Also was introduce New Three Step Search (NTSS) for motion estimation technique was produced.
