Contour-Based Large Scale Image Retrieval
The paper presents a contour-based method for large scale image retrieval. With the contour saliency map of the object, it could address the shift-invariance problem, and with hierarchical and multi-scale feature extraction, it is able to deal with the scale-invariance problem to a certain extent. Different from existing algorithms, the features used in the retrieval system contain not only loc...
متن کاملDocument Image Retrieval Based on Keyword Spotting Using Relevance Feedback
Keyword Spotting is a well-known method in document image retrieval. In this method, Search in document images is based on query word image. In this Paper, an approach for document image retrieval based on keyword spotting has been proposed. In proposed method, a framework using relevance feedback is presented. Relevance feedback, an interactive and efficient method is used in this paper to imp...
متن کاملContour Based 3D Biological Image Reconstruction and Partial Retrieval
Image segmentation is one of the most difficult tasks in image processing. Segmentation algorithms are generally based on searching a region where pixels share similar gray level intensity and satisfy a set of defined criteria. However, the segmented region cannot be used directly for partial image retrieval. In this dissertation, a Contour Based Image Structure (CBIS) model is introduced. In t...
متن کاملComparison Contour Extraction Based on Layered Structure and Fourier Descriptor on Image Retrieval
In this paper, a new content-based image retrieval technique using shape feature is proposed. A shape features extracted by layered structure representation has been implemented. The approach is extract feature shape by measuring the distance between centroid (center) and boundaries of the object that can capture multiple boundaries in the same angle, an object shape that has some points with t...
متن کاملImage Coding Based on Contour Models
The advent of the Integrated Services Digital Network (ISDN) has resulted in a resurgence of research activity in the field of image coding. The target is to transmit real time image sequences over a number (< 30) of parallel 64kbit/s channels in order to implement fast document transfer, video telephone facilities and eventually video teleconferencing. Digital images typically occupy a large a...
