Title: Method, device, and program for generating image used for collating in pattern recognition and pattern recognition using the image
Inventor: MITA TAKESHI
IPC: G06T7/00
Filed: 2003-02-13
Abstract: <P>PROBLEM TO BE SOLVED: To improve robust property of collation without increasing processing time of image collation of pattern recognition.  <P>SOLUTION: In generating image used for collating in pattern recognition, contrast difference value about different combination of two pixel in a plurality of sample images are calculated. The contrast difference value is quantized at a predetermined quantizing level and a plurality of sample quantized images are generated which have either of quantized values depending on the predetermined quantizing level as a pixel value. For every quantized value, probability of occurrence of the quantized value in each pixel of the plurality of sample quantized image is calculated and a sample rate image having the calculated occurrence probability value as a pixel value is generated. Collation with an object image is performed by using the sample probability image.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Filed: 2003-02-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of producing a preform for a composite material having excellent gas permeability for preventing the occurrence of blow holes in a composite material and high strength.  <P>SOLUTION: Alumina fibers 2 or/and carbon fibers, titanium dioxide particles 4 and aluminum powder 3 are mixed to form an almost homogeneous premixture 9. The premixture 9 is sintered, so that the titanium dioxide particles 4 and the aluminum powder 3 are brought into oxidation-reduction reaction to produce alumina (aluminum oxide) and a titanium-nitrogen compound. The alumina (aluminum oxide) and titanium-nitrogen compound are joined to the surfaces of the alumina fibers 2 or/and carbon fibers, so that a preform 1 for a composite material is produced. The preform 1 for a composite material produced by the production method has excellent strength and gas permeability. Thus, the occurence of blow holes (voids) can be prevented in the composite material formed by the impregnation of the molten metal 13 of an aluminum alloy or the like, and the composite material can exhibit high strength.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
