چکیده

Searching interested images based on visual properties of images is a challenging problem and it has received considerable attention from researchers in the fields like image processing, computer vision and multimedia systems in the last 20 years.‎ While the importance and the effect of the image features like color, texture and shape have been taken into account in many papers, there have not been many studies on the importance of the color spaces on the performance of Content Based Image Retrieval (CBIR) systems.‎ In this paper we first experimentally study the effect of choosing color space on the performance of content based image retrieval using Wavelet decomposition of each color channel.‎ To this end, the retrieval results of different color spaces like RGB, YUV, HSV, YCbCr and Lab are analyzed.‎ Then as a result a new Content Based Retrieval model using Wavelet Transform in Lab color space and Color Moments is proposed.‎ In order to increase the efficiency of the proposed model some division schemes are taken into account which improves the performance of the proposed model.‎ The proposed model tackles one of the important restrictions in content based image retrieval, namely, the challenge between the accuracy of retrieval and its time complexity.The experimental results on two databases [19]‎ [24]‎ demonstrate the superiority of the proposed model compared to existing models.‎
