Title: Kazuhiro Ueda: Innovator in Document Image Processing
Introduction
Kazuhiro Ueda is a prominent inventor based in Toyokawa, Japan. He has made significant contributions to the field of document image processing, holding a total of 7 patents. His innovative work focuses on recognizing the orientation of document images, which is crucial for various applications in imaging technology.
Latest Patents
One of Ueda's latest patents is a document orientation recognizing device that effectively identifies the orientation of document images. This device divides an image into multiple areas and assesses the reliability of each area for orientation detection. The reliability is determined by analyzing the shape of a histogram generated from the image data. By calculating a mean value of the modulation transfer function (MTF) for each section of the histogram, the device can accurately detect the orientation of the document image.
Another notable patent is an image processing apparatus and image forming apparatus that also recognize the orientation of document images. This apparatus includes a binarization processing unit that operates separately from a pseudo gradation processing unit. The binarization processing unit uses a higher threshold for binarizing image data, allowing for the generation of histograms that depict the density distribution of the document image. The orientation is then recognized through these histograms, enhancing the accuracy of document processing.
