Patent JP-S60105082-A (JP)
Title: Contour extracted picture processor
Inventor: GOTOU TOSHIYUKI
IPC: G06T5/20
Filed: 1983-11-14
Abstract: PURPOSE:To attain the stable extraction of contours at a comparatively high speed by varying the window form of a noise eliminating circuit and estimating an optimum window form based on the density dispersion of a background. CONSTITUTION:An input part 12 converts the pincture signals supplied through a TV camera, etc. into digital pictures. A window deciding part 13 calculates the dispersion value sigma of the density of an input background part 10 through a dispersion calculating circuit 13-1. An estimating circuit 13-2 calculates a distribution of density differences at the nearby points from the value sigma in case the mediam filter processing is applied to an original picture. A deciding circuit 13-3 estimates the effect of noise from the distribution of density differences when an edge is detected. Thus the size of an optimum window is delivered for a mediam filter. In this case, the threshold value and the filter form are given from a setting part 15. Thus the selected filters are supplied. A mediam filter circuit 14-1 deletes the random noise. A primary differential arithmetic circuit 14-2 detects the density slope of each picture element, and an edge detecting circuit 14-3 detects an edge through comparison with the set threshold value.

Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a heating element having a heat resistant electrode part and a filtering function by forming an electrode part having a first layer of Ag formed by a spattering method or the like and a second layer formed on the first layer by Ag plating or the like, on a surface of a porous SiC as a sintered body having the porosity and average pore diameter respectively in specific ranges. SOLUTION: Porous SiC is a sintered body having a porosity of 30-60%, and an average pore diameter of 5-15 μm. As a first layer 1a is formed by a spattering method or the like, a metallic thin film can be formed on a surface layer, which prevents the impairing of a filtering function. As a second layer 2a composed of Ag or including Ag is formed on the first layer 1a by an Ag pasting method or the like, the adhesive force with SiC can be ensured, and further as Ag has oxidation resistance, the resistance is hardly changed even under an environment of high temperature. The metallic thin film formed on only the surface of the porous SiC sintered body 2 by the spattering or the like, of the conductive metal, can be effective as the backing surface preparation of an Ag pasting method or an Ag plating method.
