Conversion device and method converting a two dimensional image to a three dimensional image

Abstract: Disclosed is an image conversion device and method converting a two-dimensional (2D) image into a three-dimensional (3D) image. The image conversion device may selectively adjust illumination within the 2D image, generate a disparity map for the illumination adjusted image, and selectively adjust a depth value of the disparity map based on edge discrimination.

Displacement measuring apparatus, displacement measuring method, and program

Abstract: PROBLEM TO BE SOLVED: To provide a displacement measuring method capable of simultaneously measuring displacement of a plurality of evaluation points even in a measuring object in a red heat state.SOLUTION: Image component determination means 3b divides image data obtained by capturing images of a measuring object 1 before and after read heat using a digital camera 2, into RGB components respectively; and determines a component with the smallest change in a luminance value of the red heat area before and after the red heat. Image conversion means 3c converts the image data obtained by capturing the images of the measuring object 1 before and after deformation into image data of the component determined by the image component determination means 3b. Deformation computing means 3 performs pattern matching processing using the converted image data of the measuring object before and after the deformation and calculates the deformation.

Character recognition method and device based on principle of isomorphism, and terminal equipment

Abstract: The embodiment of the invention provides a character recognition method and device based on the principle of isomorphism, and terminal equipment. The method comprises the steps: obtaining a characterimage, and carrying out the preprocessing of the character image; converting a preprocessed character image into a structural map corresponding to the character image; removing a junction in a stackedmanner in the structural map, and carrying out the merging of sides; converting the structural map into a curve structural map after removing; extracting an isomorphism group which is isomorphic witha to-be-recognized curve structural map from the obtained training result set; obtaining a matched character group corresponding to the to-be-recognized curve structural map according to the extracted isomorphism group; selecting a matched character which has the minimum difference degree with the curve structural map from the obtained matched character group, and taking the matched character asa character represented by a to-be-processed character image. According to the character recognition scheme, the method achieves the recognition of the character image through the character image conversion, junction elimination, isomorphism detection and difference comparison, and improves the character recognition accuracy.

Radiation image conversion panel and radiation image diagnostic system

Abstract: A phosphor layer of a radiation image conversion panel has a thickness of 100 to 300 μm and a relative density of 65 to 80%. When a radiation image taken on the conversion panel is reproduced, the size of excitation light d for reading the radiation image satisfies the expressions: d≧ 5 r and d≦ 3 p wherein r is the average column diameter of the columnar crystals in the phosphor layer of the radiation image conversion panel and p is the pixel size of the reproduced image. The radiation image conversion panel and a radiation image diagnostic system using such a conversion panel are suitable for an application such as mammography in which soft tissue is imaged as the principal subject with low radiation energy.
