In traditional database systems, as in deductive databases that do not contain recursive rules, the eecient retrieval of tuples satisfying a constraint such as \retrieve all people who earn more than 30,000 dollars" is crucial to the performance of the database system. We investigate an algorithm which permits the \early use" of constraints to guide a(More)
Digital camera needs fixed bit rate. In this paper image compression is done using slant transform exploiting the characteristics of Human Visual System (HVS). Normally JPEG compressors support variable bit error rate. The error rate range in this compressor is found to be around -50 to 50. The error rate is reduced to around -0.6 to 1 using fuzzy logic.(More)
