摘要： A layout analysis program, a layout analysis apparatus, layout analysis method and a medium can highly accurately extract a text block from an image if the image is a color image. The layout analysis program causes a computer to execute a divided region extracting step that extracts a region partitioned by a pattern according to a binary image so as to use the outcome of extraction as divided region, a set of character elements extracting step that extracts a set of the character elements extracted by a first binary image layout analysis process for each extracted divided region so as to use the outcome of extraction as set of character elements, a text block extracting step that extracts a region including the extracted set of character elements in each divided region so as to avoid overlapping the non-character elements extracted by a second binary image layout analysis process and use the outcome of extraction as text block and a layout information generating step that generates layout information according to the text block and the non-character elements extracted by the second binary image layout analysis process.

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.

摘要： A pointing information extraction unit extracts pointing information indicating a pointing position and a pointing time on a slide from a slide file used in a lecture and a video file of a lecture video using a pointing device. A word information generation unit analyzes a text sentence extracted from the slide file to generate a word information file indicating a word and a position thereof. A word pointing information generation unit estimates a word closest to the pointing position on the slide to generate a word pointing information file with the pointing time assigned. A fill-in-the-blank word extraction unit extracts a word having a pointing time equal to or longer than a predetermined time from the word pointing information as a fill-in-the-blank word file. A fill-in-the-blank test question is generated by setting the fill-in-the-blank word of the slide information as a blank region.
