HSV Color Motif Co-Occurrence Matrix for Content based Image Retrieval
نویسندگان
چکیده
In this paper, HSV based color motif co-occurance matrix (HSV-Motif) is proposed for content based image retrieval (CBIR). The HSV-Motif is proposed in contrast to the RGB based color motif co-occurance matrix (RGB-Motif). First the RGB (red, green, and blue) image is converted into HSV (hue, saturation, and value) image, then the H and S images are used for histogram calculation by quantizing into Q levels and the local region of V (value) image is represented by sevn motif, which are evaluated by taking into consideration of local difference between the pixels. Motif extracts the information based on distribution of edges in an image. Two experiments have been carried out for proving the worth of our algorithm. It is further mentioned that the database considered for experiments are Corel 1000 database (DB1), and MIT VisTex database (DB2). The results after being investigated show a significant improvement in terms of their evaluation measures as compared to RGB-Motif.

Image retrieval using the combination of text-based and content-based algorithms
Image retrieval is an important research field which has received great attention in the last decades. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywords and for content-based features, color and texture features have been used. Query in this system contains some keywords and an input...

In the present days, Images are widely used everywhere. The Image retrieval are classified into content based image retrieval that is using image contents such as color, texture, shape and spatial information and context based image retrieval that is using annotated text. Content Based Image Retrieval (CBIR) is a well-known technique for effective image retrieval. The fused features are used to...

Article history: Available online 25 December 2012 In this paper, the modified color motif co-occurrence matrix (MCMCM) is presented for content-based image retrieval. The proposed method collects the inter-correlation between the red, green, and blue color planes which is absent in color motif co-occurrence matrix. The proposed method integrates the MCMCM and difference between the pixels of a...

In case of large image database, text based image retrieval is proven to be insufficient. For large data base assigning the labels to each image using text is extremely time consuming. It is applicable for only one language at a time. Different users can assign different labels to the same image. To overcome these drawbacks, content based image retrieval method is used. There are two types of f...
