Thus, it is evident that imae performance of these methods can be improved by differentiating the edges in more than two directions. International journal of computer vision 73 2, LBP is a two-valued code.
The results can be further improved by considering the diagonal pixels for derivative calculations in addition to horizontal and vertical directions. Texture analysis able to extracts the texture features namely contrast, directionality, coarseness and busyness and it is applicable in computer vision, pattern recognition, segmentation and image retrieval.
Retrieeval images of memory size LBP method is gray scale invariant and can be easily combined with a simple contrast measure by computing for each neighborhood the difference of the average gray level of those pixels which have the value 1 and those which have the value 0 respectively as shown in Figure.

Local Grayvalue Invariants for Image Retrieval
Here, horizontal and vertical pixels have been used for imagf calculation. Applied to indexing an object database Cordelia Schmid Indexing allows for efficient retrieval from a database of more than 1, images.
The term ‘content’ in this context might refer to colors, shapes, graycalue, or any other information that can be derived from the image itself. 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.
