What Is Jpeg Encoder?

1.	What Is Jpeg Encoder?
Answer» JPEG encoder has three main blocks namely, FORWARD Discrete Cosine TRANSFORM, Quantizer and Entropy Encoder. JPEG encoder is the main COMPONENT for lossless and hierarchical ENCODERS. It is suitable for gray scale and color images. Each image is divided into 8 x 8 blocks. A group of 4 tables are specified by JPEG. If the table has quality value with 1, then the quality is best and compression is lowest. If the table has quality value with 2, then the quality is best and compression is HIGHEST.
