Define Source encoder in image-processing

Question

Define Source encoder.

Answer 1

            Source encoder performs 3 operations

1)      Mapper this transforms the input data into non-visual format. It reduces the interpixel redundancy.

2)      Quantizer- It reduces the psycho visual redundancy of the input images. This step is omitted if the system is error free.

3)      Symbol encoder – This reduces the coding redundancy. This is the final stage of encoding process.
