摘要： The present invention as disclosed hereby is to provide an apparatus and method for allowing images to correspond to each other and a program therefore to automatically perform or make synchronous correspondence of images. According to the apparatus on the condition that there are OHP files and a moving image photographing a lecture or the like using such OHP files, resemblances between the OHP files and OHP image regions of frame images constituting the moving image is calculated such that the correspondence processing between the OHP files and the frame images can be performed based on the calculated resemblances.

摘要： A method and apparatus for generating a degraded character image at various levels of degradation automatically is presented in this invention. The method comprises rendering the character image on a scene plane; translating and rotating the scene plane according to various parameters; determining a projection region of the character image on an image plane according to various parameters; generating a pixel region mask; and generating a final degraded image by super-sampling. Thus various degraded character images are generated on various conditions of degradation. The generated synthetic characters can be used for performance evaluation and training data augmentation in optical character recognition (OCR).

摘要： A ruled line extracting apparatus obtains circumscribed rectangles of pixel concatenation regions included in an input pattern, and calculates the most frequent value of their heights. Additionally, the apparatus integrates segments by ignoring a wild card segment, and calculates the most frequent value of height/width of extracted straight lines and segments structuring the straight line. Next, it performs a process for integrating/deleting straight lines using each threshold value based on the highest frequency value. Then, it checks/deletes a straight line according to a distribution of black pixels around the straight line, and recognizes the remaining straight lines as ruled line candidates.

摘要： A management information extraction apparatus learns the structure of ruled lines of a document and the position of user-specified management information such as a title, etc. during a form learning process, and stores them in a layout dictionary. During the operation, the structure of the ruled lines extracted from an image of an input document is matched with that of the document in the layout dictionary. Then, position information in the layout dictionary is referred to, and the management information is extracted from the input document.

摘要： A telop character extraction apparatus generates a gray-scale image from a telop region image, and generates an edge region image where an edge is extracted from within the gray-scale image. The apparatus uses the edge region image as a mask image, and creates a luminance histogram of pixels of the gray-scale image. The apparatus divides a luminance of the luminance histogram into luminance classes. The apparatus generates binary images where pixels of luminances belonging to the individual classes are collected for the respective luminance classes, and selects the binary image of the class of maximum area, as a telop character candidate image. The apparatus decides on a character color used in the telop region image, in correspondence with the telop character candidate image, and extracts character pixels corresponding to the character color, from within the telop character candidate image, thereby to eliminate noise pixels and to generate telop character image.
