Spot detection is an essential step in 2-DE gel image analysis. The results of protein spot detection may substantially influence subsequent stages of analysis. This study presents a novel method for spot detection with the addition of confidence evaluation for each detected spot. The confidence of a spot provides useful hints for subsequent processing,(More)
Fractal image compression exploits the self-similarity of an image to achieve the purpose of compression. In the standard algorithm, eight Dihedral transformations are applied on domain blocks to increase the codebook size, and therefore, the quality of reconstructed image can be improved. However, such mechanism consumes approximately eight times of the(More)
Many countries are experiencing a rapid increase in their elderly populations, increasing the demand for appropriate healthcare systems including fall-detection systems. In recent years, many fall-detection systems have been developed, although most require the use of wearable devices. Such systems function only when the subject is wearing the device. A(More)

Access to electronic books, electronic journals, and web portals, which may contain graphics (drawings or diagrams) and images, is now ubiquitous. However, users may have photographs that contain graphics or images and want to access an electronic database to retrieve this information. Hence, an effective photograph retrieval method is needed. Although many(More)
