Planar shape indexing and retrieval based on Hidden Markov Models
نویسندگان
چکیده
This paper presents a planar shape recognition method for content based image retrieval in multimedia databases. Shapes are characterised by their corners, which are extracted from the curvature function of their contours. Then, corner sequences are compared by using Hidden MarkovModels so that the process is resistant against corner shifting and loss. The proposed method has been successfully tested over publicly available databases.

متن کاملImage Retrieval Using Circular Hidden Markov Models with a Garbage State
Shape-based image and video retrieval is an active research topic in multimedia information retrieval. It is well known that there are significant variations in shapes of the same category extracted from images and videos. In this paper, we propose to use circular hidden Markov models for shape recognition and image retrieval. In our approach, we use a garbage state to explicitly deal with shap...
متن کاملDate-field retrieval in scene image and video frames using text enhancement and shape coding
Text recognition in scene image and video frames is difficult because of low resolution, blur, background noise, etc. Since traditional OCRs do not perform well in such images, information retrieval using keywords could be an alternative way to index/retrieve such text information. Date is a useful piece of information which has various applications including date-wise videos/scene searching, i...
متن کاملAutomatic Linguistic Indexing of Pictures by a Statistical Modeling Approach
Automatic linguistic indexing of pictures is an important but highly challenging problem for researchers in computer vision and content-based image retrieval. In this paper, we introduce a statistical modeling approach to this problem. Categorized images are used to train a dictionary of hundreds of statistical models each representing a concept. Images of any given concept are regarded as inst...
