摘要： In a system for segmenting a pixel based image, pixels containing image boundaries are identified. The image boundaries are then fattened by repeatedly adding fattening rows of pixels to the pixels containing boundaries to separate the remaining pixels into separate segments. The separate segments are then grown back to their original size before the boundaries were fattened. This operation has the effect of linking the boundaries together to separate the image into segments and to extend incomplete boundaries into complete boundaries around segments in the image.

摘要： A method for image processing to facilitate expression with more reality of sense of distance by blurring is provided. In the method according to the invention, image data having far and near distance information of the image are processed by a digital low-pass filter having a cut-off frequency corresponding to the distance information, so that a blurred image based on the distance information is formed.

摘要： An apparatus for converting gray levels of an image, a method thereof, a program storage device thereof, and an infrared camera. The object of the present invention is to provide an apparatus for converting gray levels into fewer gray levels without missing a local gradation, a method thereof, a program storage device thereof, and an infrared camera to which the present invention is applied. A positive mask image (C) and a reversed mask image (C′) are obtained the edge detected image (B) which is produced by emphasizing edges of an original image (A). A low frequency component (D) is obtained by performing an edge preserving smoothing operation for A masked with C, and performing a non-edge preserving smoothing operation for A masked with C′. A high frequency component (E) is obtained by calculating of (A-D). After D is compressed to D′ and E is emphasized to E′, an output image (F′) is obtained by adding D′ and E′.

摘要： A method for mapping a boundary for a multi-pel thickness line into a bitmap image which describes the pel boundary with respect to an orthogonal pel array. The line has thickness T centered around a spine between a start and stop point. The boundaries for the rounded ends of the line are determined by centering a pre-stored T-diameter pel dot boundary with respect to the start and stop points. The rounded end boundaries are tangentially connected by a first pair of sides of a rectangular perimeter whose remaining two sides diametrically intersect the dot boundaries. The start point, the thickness, and line slope are utilized for estimating and mapping four corner points of the rectangular perimeter with respect to the orthogonal pel array. The vertical orientation of the mapped corner points designate up to five sections of the line boundary including two end sections, one of which lies above an uppermost corner point, and the other below a lowermost corner point. Both end sections are mapped according to the corresponding pel dot boundary as centered at the start and stop points. A middle section has a first straight sliding edged determined according to Bresenham's algorithm and a second straight edge determined by adding the fixed horizontal width of the line to te horizontal position of the first edge. For each of the remaining two sections, one edge is estimated and mapped utilizing Bresenham's algorithm and the other edge is mapped in according to the corresponding

摘要： Noise in digitized image data is reduced by providing an array of pixels for each of which a gray level has been determined. For each column of the array, a distribution of gray levels is derived, and a range of acceptable gray levels is set based on the distribution. For pixels with a gray level outside the range, the gray level is changed to reduce the influence of noise in the imaged data.

摘要： Pixel data representative of a discrete pixel image is processed to identify structures and non-structures in the image defined by the pixel data. The structures and non-structures are processed in different manners. The structures are identified by computing gradient information on each pixel and by comparing the gradient information to a gradient threshold, and by comparing gradient directions for adjacent pixels to one another. The edges defining the structures are binary rank order filtered. The structures are orientation smoothed and sharpened. The non-structures are homogenization smoothed and original texture is blended back into non-structural regions.
