An apparatus for inspecting the characters/numbers of a negotiable instrument, the apparatus being provided with: cameras () for imaging the character/number sequence () printed on each design on large-size printed matter () on which a plurality of designs of the negotiable instrument are printed; and a character/number inspection device () for determining the suitability of the characters/numbers printed on each negotiable instrument on the basis of the image data imaged by the cameras (), wherein the character/number inspection device () determines the suitability of the character/number sequence () in a cut segment () on the basis of a plurality of determination standards set in accordance with the position of the cut segment () on the large-size printed matter ().

Apparatus for inspecting characters/numbers of negotiable instrument, and method for inspecting characters/numbers of negotiable instrument

Provided is a method for removing character background in a color image that obtains an image for printing evaluation by removing a background design of a character from the color image of a printed object on which the character has been printed. The method includes separating a color input image into a character part and a background part, calculating a discriminant function for separating pixels of the character part and pixels of the background part based on pixel values, and generating a background-removed image by removing the background part from the input image by using the discriminant function. Moreover, an installation adjustment method of a line camera including adjusting, based on a signal acquired by capturing an installation adjustment chart fixed to the inspection drum, an installation position of the line camera that acquires an image of a large-size printed object arranged on an inspection drum, is executed by using an installation adjustment chart wherein a plurality of patterns formed by white background and black vertical lines are arranged by shifting in a vertical direction so that the vertical lines continue horizontally only in a predetermined rectangular region that is elongated in a scan line direction of the line camera.

Method and apparatus for removing character background from colored image

In the apparatus for searching corresponding points between an input image and a reference image, a reference image and an input image are received through an image input section. The division process section produces a reference partial image and an input partial image. The similarity degree image production section respectively produces similarity degree images whose similarity degree between the reference partial image and the input partial image. The accumulation-addition processing section recursively performs an accumulation-addition of a plurality of similarity degrees. Based on the result, the corresponding points determination section determines the corresponding points between the input image and the reference image.
