AN EFFICIENT CONTENT BASED IMAGE RETRIEVAL USING LOCAL TETRA PATTERN

T.Prathiba, G. Soniah Darathi

The explosive growth of digital image libraries increased the requirements of Content based image retrieval (CBIR). It can automatically search the desired image from the huge database. This paper proposes an advanced image retrieval using Local Tetra Pattern (LTrP)s. It develops a strategy to compute n-th order LTrP using (n-1) th order horizontal and vertical derivatives and it derives an efficient CBIR. The previously declared Local Binary Pattern(LBP) can able to encode the images with two distinct values and Local Ternary Pattern(LTP) can encode images with only three distinct values but the LTrP encoded the images with four distinct values as it is able to extract more detailed information.
