    Abstract: PROBLEM TO BE SOLVED: To provide a new and improved method for automatic detection of the exact boundary of a chest part in a digitized chest part X-ray picture. SOLUTION: This is a computerized method for detecting and characterizing a disease by a picture obtained from a chest part X-ray picture. The picture in the chest part X-ray picture is processed for deciding the boundary of the chest part including the edge of a lung upper end, right and left chest part edges, and right and left half diaphragm edges. An organizational scale including the RMS change of pixel values in a concerned area is converted into relative exposure, and a system noise component which is present in a system used for the generation of the picture is compensated. An organizational index and a geometrical pattern index are generated. Also, the histogram of the index is generated, and inputted to a learned artificial neural network for classifying the normality and abnormality of the picture to be applied.

    Abstract: PURPOSE: To enable an anatomically abnormal region to be automatically detected by specifying a plurality of locations in a digital image having a possibility as an abnormal region through digital image processing of a subject having an anatomically abnormal region, and by deciding an edge gradient to each region and comparing their threshold values. CONSTITUTION: In the case that a position of cluster containing a signal of a microcalcified part is detected, firstly, it is photographed by an X-ray system and a signal extraction processing 300 is carried out after producing a differential image 200 imputting a digital mammogram 100 digitalized by a laser scanner. Next, with a possible location as a microcalcified part which becomes a problem in the differential image specified, the differential image data in the circumferential region of the specified location is processed in a characteristic extraction processing 600. Next, an area vs contrast test 700 and a contrast vs background test 800 are carried out and a cluster is processed in highlighting by carrying out a cluster filter processing 900.

    Abstract: A method and system for monitoring an industrial process and a sensor. The method and system include generating a first and second signal characteristic of an industrial process variable. One of the signals can be an artificial signal generated by an auto regressive moving average technique. After obtaining two signals associated with one physical variable, a difference function is obtained by determining the arithmetic difference between the two pairs of signals over time. A frequency domain transformation is made of the difference function to obtain Fourier modes describing a composite function. A residual function is obtained by subtracting the composite function from the difference function and the residual function (free of nonwhite noise) is analysed by a statistical probability ratio test.

    Abstract: A method and system for automated detection and classification of masses in mammograms. This method and system include the performance of iterative, multi-level gray level thresholding (202), followed by lesion extraction (203) and feature extraction techniques (205) for classifying true masses from false-postive masses and malignant masses from benign masses. The method and system provide improvements in the detection of masses including multi-gray-level thresholding (202) of the processed images to increase sensitivity and accurate region growing and feature analysis to increase specificity. Novel improvements in the classification of masses include a cumulative edge gradient orientation histogram analysis relative to the radial angle of the pixels in question; i.e. either around the margin of the mass or within or around the mass in question. The classification of the mass leads to a likelihood malignancy.
