Abstract :
The point of this project was to create
algorithm that will produce some improvement in quality
of JPEG image, by removing blocking artifacts JPEG
decompressed images. The obstructing effect are grouped
into three sorts of noise: staircase artifact, corner outlier,
grid artifact. The proposed algorithm removes these
blocking effects efficiently. The postprocessing algorithm
comprise of three stages. In this project we will learn
about compression and decompression of JPEG images.
For compression we have used the Discrete cosine
transform (DCT) technique using the Huffman algorithm
and adaptive filter. Converting the image into a 2d matrix
using Discrete cosine transform (DCT) and DCT2 and
then removing redundant values according to the
algorithm. We have then used Inverse discrete cosine
transform (IDCT) to form the compressed image.
