A simple implementation of the algorithm JPEG encoder/decoder.
- Opencv Opencv package utilized in reading/show of images and conversion of colors spaces RGB to YCbCr.
- Bitstring package used to convert the coefficients of the DCT transform.
Just run the main file.
python main.py
Generates a generic text (and large) file '.huff' in 'output/' with the binary stream. Coputes some compression information like: compression rate, data redundancy, total number of bits. At the end the image quality is measured by performing the Structural Similarity Index are performed.
