摘要： A method of segmenting characters of a document image comprises the steps of dividing the document image into a plurality of divided regions and setting a check width with respect to each of the divided regions, where each check width is greater than or equal to a width of a corresponding one of the divided regions so that the check widths of two mutually adjacent divided regions partially overlap each other, reading image data amounting to one line of the document image, obtaining from the image data horizontal projections of each line data within each of the check widths, where each horizontal projection is a number of black picture elements in a corresponding data line within a check width and each data line is made up of a plurality of picture elements arranged horizontally, segmenting a line based on the horizontal projections, obtaining from the image data vertical projections, where each vertical projection is a number of black picture elements in a vertical direction, determining a character segmentation range based on the vertical projections, and segmenting each character of the line within the character segmentation range.

摘要： A pattern recognition method comprises a contour tracing step of a contour of a binary image in a predetermined direction along a predetermined type of pixels. At this time, four adjacent pixels on upper, lower, left-hand and right-hand sides of a point of interest are sequentially checked. Then, one pixel of a predetermined type out of the four adjacent pixels which is the first pixel of the predetermined type found by the check is designated as a next trace point subsequent to the point of interest. In this process, a feature of each of the traced pixels is extracted. The feature is represented by a directional code which indicates a direction of motion from the point of interest to the next trace point. The features are successively registered in a one-dimensional form. Histogram is produced for each sub-region storing a part of the one-dimensional feature sequence. A histogram for each sub-region is compared with a related reference histogram for a known character.

摘要： In a method of extracting feature quantities of a character, a pair of region dividing lines which intersect a character image are obtained by using generated projections of direction codes. Then, a reference position for extracting feature quantities of the character is decided by finding positions at which the region dividing lines intersect the character image. Thereafter, the feature quantities of the character having the reference position are extracted by subjecting the codes of the divided segments to a predetermined operation for obtaining information regarding a shape of each of the divided segments.

摘要： An apparatus for heating a baby formula pot 10 includes a case 11, and a heating plate 12 disposed in the case 11 on which a baby formula pot 30 is mounted. When the baby formula pot 30 is mounted on the heating plate 12 and is heated by the heating plate 12, the water contained in the baby formula pot 30 is boiled to become hot water. An water amount is calculated by a control mechanism 35 based on a temperature rising ratio of the water. An optimum cooling period is calculated by the control mechanism 35 based on the calculated water amount. A cooling fan 13 is rotated by the control mechanism 35 in compliance with the optimum cooling period, so that the baby formula pot 30 is cooled by air taken-in through air intake ports 18.

摘要： An input, unknown character is optionally read to form a binary character image, and a plurality of directionality codes are assigned to pixels defining the contour of the character image selectively to define a code-assigned character image, which is then subdivided into a plurality of sub-regions in the form of mesh such that each sub-region includes a substantially equal number of assigned codes. Then, a histogram of the codes is defined for each of the sub-regions to form a collection of histograms for the input character. The input character is compared with each of registered, known characters, each having a collection of similar histograms, and the one having a greatest similarity is selected to identify the input character. The similarity is determined by calculating a distance between the histograms of the input character and the histograms of the each of the registered characters. Preferably, the binary character image is subjected to line-broadening processing prior to the step of assigning the codes.
