On the selection of image compression algorithms
Image compression: Lossy vs Lossless
Wavelet compression
Wavelet compression
JPEG Compression (DCT)
JPEG Compression (DCT)
VQ Compression
Codebook -> codevectors -> 4x4 discribed by codevecors
Fractal Compression
Fractal Compression
+ -
Wavelet transform, JPEG (DCT):
- + Compresie buna
- + Calitate buna
- + Durata mica
VQ Compression:
- - Durata mare de timp
- + Compresie foarte buna
- + Calitate buna
Fractal compression:
- + Compresie foarte buna
- + Calitate buna
- - Durata foarte mare de timp
DCT for image similarity
Multumesc!
