Describe the individual sketch method and try to integrate this method for reducing the individual methods drawback. Keywords: EHD, HOG, Proposed System, Result of Proposed System. I. Introduction The content based image retrieval (CBIR) is one of the most popular, rising research areas of the digital image processing. Most of the available image search tools, such as Goggle Images and Yahoo! Image search, are based on textual annotations of images. In these tools, images are manually annotated with keywords and then retrieved using text- based searching methods. The performances of these systems are not satisfactory. The goal of CBIR is to extract visual content of an image automatically, like color, texture, or shape. This paper aims to introduce the problems and challenges concerned with the design and the creation of CBIR systems, which is based on a free hand sketch (Sketch based image retrieval – SBIR). With the help of the existing methods, describe a possible solution how to design and implement a task specific descriptor, which can handle the informational gap between a sketch and a colored image, making an opportunity for the efficient search hereby. The used descriptor is constructed after such special sequence of pre-processing steps that the transformed full color image and the sketch can be compared. We have studied EHD and HOG. Experimental results on two sample databases how good results. Overall, the results show that the sketch based system allows users an intuitive access to search-tools. II. Some Sketch Methods In the Existing Method we can perform some changes to improving its efficiency Modified EHD: EHD: is the Edge Histogram Descriptor method. Here we describe the block diagram of EHD.
