چکیده
Compressing the image causes less memory to be used store images. images increases transmission speed of compressed in network. Vector quantization (VQ) is one compression methods. The challenge vector method for non-optimization codebooks. Codebook optimization quality and reduces volume Various methods swarm intelligence meta-heuristics are improve algorithm, but using meta-heuristic based on mathematical sciences has history. This paper uses an improved sine–cosine algorithm (SCA) version optimize reduce error. reason SCA balance between search exploration exploitation by sine cosine functions, which makes it likely get caught local optima. proposed calculation error spiral trigonometric functions a new helix. searches optimal solutions with snail searches, increasing chances finding more solutions. aims find codebook VQ algorithm. advantage codebooks implementing MATLAB software, experiments showed that method's PSNR index improves algorithm's ratio 13.73%. Evaluations show higher better than PBM, CS-LBG, FA-LBG, BA-LBG, HBMO-LBG, QPSO-LBG, PSO-LBG. result shows (or ISCA-LBG) time complexity HHO WOA algorithms.

Vector Quantization (VQ)
The important point about VQ is that, we require reproduction vectors (instead of reproduction levels) that are known by the encpder and the decoder. The encoder takes an input vector, determines the best representing reproduction vector, and transmits the index of that vector. The decoder takes that index, and forms the reproduction vector because it already knows the reproduction vectors inst...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

In this paper, an image compression scheme is proposed, based on discrete cosine transform (DCT). This scheme is a hybrid method, which combines vector quantization (VQ) and differential pulse code modulation (DPCM). This scheme begins with transforming image from spatial domain to frequency domain using DCT. Then the block data is transformed into a vector according to zigzag order, and then t...
