摘要： A method for locating symbols arranged in one or more rows in an image includes smearing the image, and fitting line segments through edge points of features in the smeared image. A group is found of the line segments that are in mutual proximity and are mutually substantially parallel. A region of the image that contains the group of the line segments is identified as a possible location of the symbols.

摘要： A spatial filtering method providing quick detection and visualization of irregularities of SEM images of components such as integrated circuits includes the steps of: (a) acquiring a digital image as a two-dimensional array of pixel data from an original image; (b) calculating a first Fourier transform to generate a two-dimensional array of complex data; (c) calculating a power spectrum to provide a real function representing a weighting of each spatial frequency in the original image; (d) generating a mask for suppressing regular structures of the original image and undesirable artifacts introduced by the acquiring of the digital image in step (a); (e) dilating the mask generated in step (d) by extending masking spots generated therein to increase the suppression of regular structures of the original image; (f) applying the mask dilated in step (e) to the data from the first Fourier transform for removing periodic data to result in a second Fourier transform; (g) calculating an inverse Fourier transform of the data of the second Fourier transform to obtain a spatially filtered image; (h) scaling the spatially filtered image to greyscale; and (i) providing a visual representation of the greyscaled image obtained in step (h).

摘要： A foreground erosion method is used to meet thin (but unbroken) text requirements using linear YCC segmentation. The method uses a fixed value subtracted from a gray selector signal, thereby thinning/eroding the foreground. In cases where the pixel would be converted from foreground to background, this is only done if a neighborhood test verifies that the thinning won't result in broken lines. The foreground erosion method attempts to match a couple of templates wherein if a match is found, then the adjustment is performed.

摘要： Methods, code and apparatus analyze cell images to automatically identify and characterize the Golgi complex in individual cells. This is accomplished by first locating the cells in the image and defining boundaries of those cells that subsume some or all of the Golgi complex of those cells. The Golgi complex in the images typically have intensity values corresponding to the concentration of a Golgi component in the cell (e.g. a polysaccharide associated with the Golgi complex). The method/system then analyzes the Golgi components of the image (typically on a pixel-by-pixel basis) to mathematically characterize the Golgi complex of individual cells. This mathematical characterization represents phenotypic information about the cells' Golgi complex and can be used to classify cells. From this information, mechanism of action and other important biological information can be deduced.

摘要： The image processing equipment produces an image of enhanced quality, having dots with higher density than in an original image, by collating an original image with templates. The present invention reduces required number of templates. Original image data in a collation window is either mirror-converted, flip-converted or flip-and-mirror-converted in an array converter (33) and selected on a time-division basis to collate with a single template pattern (34). The effect is equivalent to the collation with maximum four templates. Thus the number of template patterns to be prepared is greatly reduced. Also, by preparing additional patterns to be stored into an area that became vacant attributed to the reduction of patterns, more sophisticated image enhancement may be attained.

摘要： An image processing system is described in which sets of image elements having display values outside of a target range B of display values are each respectively morphologically dilated. The intersection between the morphologically dilated sets of image elements is then identified and those image elements within the intersecting region are removed from the set of image elements having the target range B of display values. This removes image elements incorrectly appearing to have display values corresponding to the target range B of display values due to aliasing effect between regions of image elements having display values either side of the target range B of imaging may be two-dimensional or three-dimensional imaging. The morphologically dilatation is preferably performed with a quasi-circular or a quasi-spherical structuring element having a radius of between two and three voxels.

摘要： A method is disclosed for determining skeletons of any two dimensional images and three-dimensional skeletons of vessel trees. In the three dimensional case, the method takes a binary volume of any vessel tree as input and produces centred, connected and one-voxel wide skeleton of the input vessel tree. In the two dimensional case, centred, connected and one-pixel wide skeletons of input binary images are produced. The method includes the steps of: (1) calculating a 3D/2D distance transform, (2) locating local maximum voxels/pixels, one-voxels/pixel, (3) propagating skeletal elements to get a full set of skeletal elements, and (4) removing redundant local maximum voxels/pixels to obtain a one-voxel/pixel wide skeleton.

摘要： To avoid generating visible artifacts in the image, such as those generated when mildly defective areas are not identified, a system and method for identifying and correcting defects in a digital image including adjusting the pixel values of pixels surrounding the defective pixels are disclosed. The method for correcting defects in a input digital image comprises the steps of identifying the defects to form at least one defect map, generating a region of interest for each defect map, correcting the values of the pixels in each defect map, and adjusting the values of the pixels in each region of interest. In one embodiment, the input digital image is filtered with a median filter to generate a filtered image. A difference image is generated by subtracting the filtered image from the input digital image, and the pixels at which the difference image pixel value exceeds a given threshold are identified as defect pixel locations. The defect maps are comprised of adjoining defect pixel locations. The pixel values at the defect pixel locations are replaced with the corresponding filtered image pixel values. A smoothing operation is applied to obtain the adjusted value of the pixels in each region of interest corresponding to each defect map. User input is utilized to further mitigate the effects of uncertainty in defect identification.
