Yes, I understand why the initial compression of a bitmap (not necessarily a .BMP) to a JPEG is lossy, via the quantization step after DCT. But if I decompress a JPEG back to a new bitmap, and then re ...

Image compression, once the domain of the PC, is becoming pervasive in embedded environments. This trend is largely a result of the increased processing power and multimedia capabilities of new DSPs.

A 3.0X times image compression method and fast storage device accessing H.265 referencing image frame is achieved by applying fixed bit rate to reduce each “Block of pixels” data of each image frame.

Compression is performed by a program that uses a formula or algorithm to determine how to shrink the size of the data. For instance, an algorithm may represent a string of bits-- or 0s and 1s -- with ...
