Abstract: Disclosed herein is a biodegradable polyolefin fiber comprising a core formed of polyolefin and an oxide layer formed outside the core according to an embodiment of the present invention. According to the present invention, the polyolefin fiber is capable of having biodegradable properties by mixing raw materials and the biodegradable additive in a specific condition. In addition, the oxide layer is formed on the surface of the polyolefin fiber, thereby improving the initial oxo-biodegradation rate and reducing the biodegradation time.

Abstract: A method for generating a block-based image histogram from data compressed by JPEG, MPEG-1, and MPEG-2, or uncompressed image data employing block-based linear quantization to generate histograms that include color, brightness, and edge components. The edge histogram, in particular, includes the global edge features, semi-global edge features, and local edge features. The global edge histogram is based on image blocks of the entire image space. The local edge histogram is based on a group of edge blocks. The semi-global edge histogram is based on the horizontally and the vertically grouped image blocks. A method for generating block-based image histogram with color information and brightness information of image data in accordance with an embodiment of the present invention extracts feature information of an image in terms of the block and updates global histogram bins on the basis of the feature information.

Abstract: Provided is a photodetector in which a transparent nonconductive material having an interface charge and a trapped charge is deposited on a semiconductor surface so as to form a depletion region on the surface of the semiconductor, and the depletion region is employed as an optical detecting region, thereby not only improving detection with respect to light having a wavelength of ultraviolet and blue ranges but also filtering light having a wavelength of visible and infrared ranges, and in which a fabricating process thereof is compatible with a universal silicon CMOS process.
