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. The method for generating block-based image histogram with color information and brightness information of image data minimizes quantization error by employing linear weight and updates values of histogram bins. The error that occurs at a boundary between bins of the histograms and the linear weight depends on the distance between the histogram bins.

The present invention relates to a hair iron adapted to reduce hair damage, strengthen hair and facilitate hair styling by blowing air toward the hair. The hair iron of the present invention is further adapted to provide hair with anions or moisture during hair styling. The hair iron includes a pair of cases hinge-jointed at each one end and being freely opened or closed, wherein each case has a heater plate for generating heat at the other end. A fan assembly for blowing air is coupled to the one end of one of the cases. An air passage through which the blown air is passed is formed inside the hair iron. An anion generator is located in the fan assembly, thereby mixing the anions with the air being transferred. Means for providing moisture is disposed adjacent to the heater plate and means for supplying the moisture-providing means with water is received in the recess formed in lower side of the case. Further, the present invention relates to a hair iron constructed without a power cord so as to be utilized without any spatial restriction while possessing all the functions of the hair iron.

Provided is a tunable external cavity laser diode using a variable optical deflector wherein the variable optical deflector, in which a refractive index varies according to an electrical signal, is arranged in a triangular shape between a concave diffraction grating and a reflective mirror. Since a resonant frequency is changed using the electrical signal rather than the mechanical movement, the stable operation and continuous high-speed tenability may be enabled. In addition, when the tunable external cavity laser diode according to the present invention is implemented in an InP/InGaAsP/InP slab waveguide, a variable time determined by the carrier lifetime may be reduced to several nanoseconds or less, the miniaturization is enabled, and the manufacturing costs are significantly reduced due to the process simplification. Moreover, when the concave diffraction grating is designed based on a silica (or polymer) based slab waveguide, the fabrication may be performed even by a lithography process having low resolution, thereby enhancing reproducibility and uniformity of the diffraction grating, and accordingly reducing the manufacturing costs.
