This paper presents a method on linear-regression model based wavelet filter evaluation for image compression. This method analyses several factors (including image’s brightness, image’s contrast, filter’s ability to concentrate energy, and entropy distribution on bit-plane of wavelet transform coefficients), and evaluates wavelet filters by predicting the quality of restored images. In this way, it provides an accurate and objective way to evaluate wavelet filter for image compression without encoding or decoding, and has certain significance on the study of evaluation and choice of wavelet filters.","PeriodicalId":120452,"journal":{"name":"Asia-Pacific Conference on Wearable Computing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127541609","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}
