A number of content-based image search methods have been proposed to this point. Each of these systems uses different image data and generates different data depending on the extraction method of different characteristics that the search capabilities of each system cannot be compared and assessed. In particular, there is a problem of applying the identical image data onto the contents based image search system on the web that cannot be compared and assessed. To resolve such a problem, the XML-based FEMAL is hereby presented for extracting data of characteristics generated from specific search system in a way that can be recognized from other starch system. In the experiment using FEMAL, the extract data for characteristics is mutually communicated and integrated and the comparison assessment of search capability is seemed to be available.

There are many ways to judge whether the input image is adult-image or not. Until now, adult image detection has been examined by the ratio of skin area in full image. In this paper, we propose a method to extract skin region in YCbCr. Skin region shows unique distribution in YCbCr, and we will separate the skin region from background using the distribution. First, we are going to find Eye zone using Eye-Map. Then we will find out the color value for the distribution of skin region using the color of Eye zone. Next, we will find the distribution of the area through the skin region in full-image.

The burst loading of a pre-created cache-image is an effective method to reduce the instruction cache misses in the early stage of the program execution. It is useful to alleviate the performance degradation as well as the energy inefficiency, which is induced by the concentrated cold misses at the instruction cache. However, there are some defects, including software overhead on the compiler and installer. Furthermore, there are several mismatches as a result of the dynamic properties for specific applications. This paper addresses these issues and proposes a cache-image maintenance/recreation policy that can conduct dynamic management using a hardware-assisted method. The results of the simulation show that the proposed method can maintain the cache-image with a proper size and validity.

In this paper, we propose a new watermarking method using isolation of invalid blocks for image authentication. We embed messages into the high frequency band in the DCT domain because of its imperceptibility and fragility. And we were able to inspect the identity of valid blocks between error corrected original images and watermarked images through experiments. As a result, we found that the watermarked image is enough to extract binary messages. Therefore, the extra information such as the original image or watermark was not necessary in our extracting process. Experiment results show that the proposed method can be used successfully for image authentication.
