sir
i am compressing the image using transforms DCT DFT and DWT. the block of operation is
take image>>sub block into 8*8 >> apply DCT >> apply Quantization >> Apply RLE >> RL decoding>> Dequantization >>IDCT >> add sub blocks
Is this process give me compression ??
if no, What i need to do for compression ?
if yes, Where exactly the compression done??
what kind of image is to be use for this process??
All the images are already got compressed when capture by camera??

No, the process does not give you compression.
Not all images are already compressed when captured by cameras.
