This allows application developers to adapt not only the software but also the hardware of the computer on an application-by-application basis. Experimental evaluation of computational speed for 2-D discrete cosine transforms of 8/spl times/8 pixel blocks within a 512/spl times/512 pixel image show that a custom computer can provide speedups of 50-100 times compared to state-of-the art computer workstations, confirming the applicability of custom computing for video processing applications.","PeriodicalId":127085,"journal":{"name":"1997 International Conference on Consumer Electronics","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121339914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We replace the discrete cosine transform (DCT) module by block-wise discrete wavelet transform (BDWT) module while keeping all the building blocks of the JPEG extension coder. In addition, we generate the variable quantization matrix (Q-matrix) based on the human visual system (HVS) and utilize the activity of the each block to control the bit and image quality. The simulation results show that the proposed scheme has substantially better performance than the JPEG extensions.","PeriodicalId":127085,"journal":{"name":"1997 International Conference on Consumer Electronics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131785847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
