A novel Image Retrieval System using an effective region ...
A novel Image Retrieval System using an effective region based shape representation technique ... A variety of methods have been proposed that enable the efficient querying of shape repositories for a desired shape or image. Many of these methods use a sample shape as a query and attempt to retrieve shapes from the database that have a similar ......
 An Efficient and Robust Technique for Region Based Shape ...
In this paper, we propose a novel approach to use contour based method for region based shape representation and retrieval. Specifically, we compute a one dimensional signature function from a region shape and use it for region shape representation and retrieval. We call it polar raster sampling signature or PRS for short. We show that...
A novel method for image retrieval based on structure ...
The multi-texton histogram (MTH) is proposed for image retrieval, MTH integrates the advantages of co-occurrence matrix and histogram by representing the attribute of co-occurrence matrix using histogram . A novel image feature detecting and describing method called micro-structure descriptor (MSD) is proposed.
Review of shape representation and description techniques ...
4. Region-based shape representation and description techniques. In region based techniques, all the pixels within a shape region are taken into account to obtain the shape representation, rather than only use boundary information as in contour base methods. Common region based methods use moment descriptors to describe shapes....
Region based Image Indexing and Retrieval System
To overcome the deficiencies of global and grid based methods, Region based image retrieval (RBIR) technique is used. In RBIR system, Image is represented at the object- level by using segmentation method to break image into objects (i.e. homogeneous regions) [6]. It contributes to more...
Content-Based Image Retrieval Using Texture Color Shape ...
image retrieval because shape is the only source through which humans can recognize objects. The shape feature can be retrieved by two methods boundary based shape feature extraction and region based shape extraction. The boundary based technique is based on outer boundary while the region based technique is depending on the whole region [16]....
Statistical Feature Based Image Classification and ...
database. proposed an approach for image retrieval from very large image database. In this paper, novel technique has been presented which uses histogram and color edge of an image with wavelet transform. Juho Kannalaet al [3] in their work presented a method for making image descriptors that effectively encode the data and also appropriate for ......
Optimal Query-Based Relevance Feedback in Medical Image ...
In image retrieval domain, the early retrieval systems carried out based on annotating text to images in database, but this method did not provide user satisfaction, because the annotation process not only is subjective task but also is tedious work and time-consuming . Moreover, a series of words do not fully describe the image content....
Perceptual Shape-Based Natural Image Representation and ...
provides a novel and efficient image feature representation. Testing on standard benchmark datasets and comparison with other well-known methods show this shape analysis method using only compact feature vectors performs well and robustly for real world images. 1 Introduction Content-based image retrieval (CBIR) is the task of au-...
A Review of Different Content Based Image Retrieval Techniques
g) S. Nandagopalan, Dr. B. S. Adiga, and N. Deepak [15]: They proposed a novel technique for generalized image retrieval based on semantic contents is offered. The grouping of three feature extraction methods specifically color, texture, and edge histogram descriptor. There is a prerequisite to include new features in future for better retrieval...
