Select an image as a query image and processing it. Each directions of center pixel will give three tetra pattern 3 0 3 4 0 3 2 0. Thus, it is evident that the performance of these methods can be improved by differentiating the edges in more than two directions.

The performance of the algorithm is evaluated on texture images. Grauvalue analysis able grayvaleu extracts the texture features namely contrast, directionality, coarseness and busyness and it is applicable in computer vision, pattern recognition, segmentation and image retrieval. Soniah Darathi 2 Assistant professor, Dept.

Computer Vision and Pattern Recognition, The LBP value is computed by comparing gray value of centre pixel with its neighbors, using the below equations 1 and 2.

Proposed method imaage the retrieval result as compared with the standard LBP also improves the average precision rate, however the algorithmic procedure much complex than LBP and LTP.

Lowe , " This paper presents a method for extracting distinctive invariant features from images, which can be used to perform reliable matching between different images of an object or scene. The features are invariant to image scale and rotation, and are shown to provide robust matching across a a substa The features are invariant to image scale and rotation, and are shown to provide robust matching across a a substantial range of affine distortion, addition of noise, change in 3D viewpoint, and change in illumination. The features are highly distinctive, in the sense that a single feature can be correctly matched with high probability against a large database of features from many images. This paper also describes an approach to using these features for object recognition.
