Image retrieval using sketched image on multimedia networks: New criteria for designing new type of TV sets

The image retrieval from the distributed image servers using a sketched ima ge was confirmed to be superior to that using keywords. In accordance with experimental and analytical studies of electronic encyclopedia, the total p rocessing time of the image retrieval using a sketched image was much short er than that of the image retrieval using keywords, and the volume of data required for the image retrieval using a sketched image was much smaller th an that for the image retrieval using keywords. Even if not familiar with E nglish, the user can easily access to the desired image databases using the sketched image at high speed, It is very important that the image retrieva l using a sketched image is not restricted by the users' ages, knowledge, a nd languages since the users can easily access to the image databases from the user terminals without keyboards. The concept of the image retrieval us ing a sketched image will provide a new criteria for designing; a new type of TV sets. This new type of TV sets, containing the multimedia user termin al functions as well as the conventional TV receiver functions, is proposed based on the results of the image retrieval using a sketched image.
