摘要： PROBLEM TO BE SOLVED: To identify whether a cut-out character candidate image is a character image or a non-character image in a short time.SOLUTION: An image in an area determined to have a possibility to be a character image is cut out as a character candidate image by a character candidate image cut-out unit 21, and normalized to a predetermined size by an image size normalization unit 22. Feature amount extractors 31-31sequentially extract feature amounts based on mutually different plural image characteristics from the normalized character candidate image. Based on the extracted feature amounts, character identifiers 32-32calculate an identification value indicating the possibility that the character candidate image is a character image or the possibility that the character candidate image is a non-character image, and compare the identification value with a threshold to identify whether the character candidate image is a character image, a non-character image, or an unknown image. When the character candidate image is identified to be a character image or a non-character image by at least one character identifier 32, a determiner 24 determines that the character candidate image is a character image or a non-character image.

摘要： PROBLEM TO BE SOLVED: To utilize advantages of both coding using irreversible frequency conversion and reversible encoding using a predictor.
SOLUTION: In coding, a source coder 101 predicts an input image per pixel using the predictor, and transmits an identifier and a prediction error as a result thereof. A frequency converter 102 uses its wavelet transform (DWT) to apply DWT processing to the prediction error transmitted from the source coder 101, and transmits it. A quantizer of the frequency converter 102 performs quantization processing to pixel values transmitted from the DWT, and transmits the values. An EBCOT 103 merges both the information in a depthwise direction in a way that a quantization index value subjected to the quantization processing for each pixel value is arranged on an LSB side, and identification information is arranged on an MSB side; executes EBCOT processing; and outputs a resulted code.

摘要： PROBLEM TO BE SOLVED: To provide an image processing apparatus for evaluating coding processing applied to image data and performing correction processing corresponding to a result of evaluation.
SOLUTION: The image processing apparatus 2 does not detect a block distortion quantity itself, but estimates quantization interval of quantization processing in the coding processing from an input image, evaluates irreversibility (deterioration in image quality) based on the coding processing, and performs correction processing corresponding to a result of evaluation. Since it is determined that, when the quantization interval is large, the image distortion is large, and when the quantization interval is small, the image distortion is small; the input image is subjected to correction processing in which the larger the quantization interval is, the stronger the strength of the processing is employed.

摘要： PROBLEM TO BE SOLVED: To provide an altered document management apparatus capable of determining the fraudulent alteration of a document on the basis of image data read from the document.
SOLUTION: TheA document management apparatus 2 uses approximately uniform light to read first image data from a document and uses light rays with which the surface of the document is irradiated obliquely, two read second image data from the document. A user displays and compares the read two image data to discriminate ruggedness (e.g. an erasure mark by an eraser) on the surface of the document. Furthermore, the document management apparatus 2 issues a time stamp certificate for a pair of two image data thus read from the same document. Thus, the authenticity of the read two image data is guaranteed.
