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 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.

摘要:
A program causes a computer to function as a document recognition apparatus, having an extraction unit for extracting connected components of pixels from an input image, a generation unit for generating a reference element that is connected components of pixels extracted by the extraction unit and combined elements obtained by combining the reference element and connected components of pixels adjacent to the reference element as an element to be estimated, a calculation unit for calculating a degree of certainty that indicates how much the element to be estimated generated by the generation unit seems to be a character, and a determination unit for identifying elements that seem to be characters among the elements to be estimated based on the degree of certainty calculated by the calculation unit.

摘要:
In an apparatus for analyzing a layout of a document, a character candidate element generator generates character candidate elements from black pixel linkage components of a document image. A horizontally oriented line rectangle generator sets a plurality of character candidate elements as a line candidate rectangle, among character candidate elements aligned in horizontal line orientation, when each amount of displacement of the set character candidate elements in a vertical orientation with respect to the horizontal line orientation, is smaller than or equal to a threshold value. A horizontally oriented paragraph-box generator sets a plurality of line candidate elements having approximately the same length as each other in the vertical orientation, as a paragraph candidate element.
摘要:
Learning material information containing a fixed attribute specifying learning materials and a variable attribute by which at least levels specifying an object person of learning are defined, is registered in a database of a learning material management system. When the learning request is received by the system from a learning applicant, with reference to the variable attribute of the learning material information registered in the database, a learning material adapted to a level of the learning applicant according to the learning request is selected to be provided for the learning applicant, and on the other hand, the variable attribute of the learning material information registered in the database is updated according to a learning result of the learning material by the learner.
摘要:
The inkjet recording liquid according to the present disclosure contains water, pigment and pigment dispersion resin. The pigment dispersion resin is alkali soluble, and is dissolved in recording liquid. The mass ratio of pigment dispersion resin to pigment (resin content/pigment content) is 0.1 to 0.3. The mass ratio of pigment dispersion resin not adhering to pigment to pigment (unattached resin/pigment content) is 0.01 to 0.1. The acid value of the pigment dispersion resin is 150 to 250 mg KOH/g. The molecular weight of the pigment dispersion resin is preferably 10,000 or more.
摘要:
An inkjet recording liquid contains water, an organic solvent, a pigment, and a pigment dispersing resin. An weight-average molecular weight of the pigment dispersing resin exceeds 30000 and is 150000 or less. A mass ratio of the pigment dispersing resin to the pigment in the recording liquid (resin content/pigment content) is 0.1 or more and 1.0 or less. An acid value of the pigment dispersing resin is 160 or more and 240 or less. The inkjet recording liquid is discharged from a recording head of the inkjet recording device. Even when nozzles of the recording head become clogged due to drying or thickening of the inkjet recording liquid, the nozzle clogging can be easily resolved with a purge operation and wiping operation of the recording head by a wipe unit. Thus, it is possible to reduce an overconsumption of the recording liquid due to the foregoing purge operation.
摘要:
An ink for an ink-jet recording apparatus contains at least water, a pigment dispersion, and a penetrating agent. The pigment dispersion contains a resin having a molecular weight of about 60,000 or more and about 150,000 or less. The ink for an ink-jet recording apparatus contains an alkanediol having 8 or 9 carbon atoms as the penetrating agent. The content of the alkanediol is about 0.2% by mass or more relative to the total mass of the ink.
