The present invention provides a method and apparatus for classifying image data. A video average may be determined from the image data. Peak detection may then be limited to an area within the image data where the video average is above a first threshold. Valley detection may be limited to an area where the video average is below a second threshold.

A machine vision method is provided for segmenting an image based on an adaptive thresholding approach that exploits prior knowledge of the characteristics, such as area, of the object to be segmented. Adaptation to varying gray-values of the candidate object/background from scene-to-scene is obtained by using a sampling window which provides gray-value statistics of the candidate object to be segmented. Next, using these statistics, a characteristic of the image of the object to be segmented, s...

A header and a payload in a cell are separated for transfer between a cell interface and a host memory. The header is transferred to a control memory. For transfer to the host memory, the control memory initially provides a host-memory region address and the region length. The payload is recorded in such region. The control memory also provides a second host-memory region address, and length, when the payload length exceeds the payload length in the first address region. For transfer from the ho...

A method and apparatus for segmenting a document which has both text and image regions. The method and apparatus implement a technique in which large text pixels and image pixels are identified in a document having a relatively low resolution. The method and apparatus then detect dark text pixels on a light background region of a document and assign segmentation labels to each pixel. The pixel labels are post-processed using a plurality of syntactic rules to correct mislabeling of pixels. This p...

A process for improving packaging efficiency uses three dimensional, computer simulated models with various optimization algorithms to determine the optimal segmentation process and packaging configurations based on constraints including container limitations. The present invention is applied to a process for decontaminating, decommissioning (D&D), and remediating a nuclear facility involving the segmentation and packaging of contaminated items in waste containers in order to minimize the number...

A cardiac segmentation system acquires a series of images acquires as slices through a volume, and as images at different time periods throughout a cardiac cycle. It displays an image to an operator which interactively selects a region of interest (ROI) of the image to be segmented, such as the left ventricle. A seed point is also selected within the ROI and the structure desired to be segmented. The image is then thresholded by a masking device classifying points within the ROI as above the thr...

A character segmentation system for segmentation out a character from a string of characters which are in touch with each other, which is capable of being executed on a small size hardware resource without influence of variation of touching condition due to difference of character font, comprises an image storing unit 110 for storing an electronic image of character string obtained by such means as optical scanning, a partial pattern dictionary 122 for storing partial pattern shapes used as feat...

Pattern segmentation and recognition in which hand-written characters are transformed electrically into 2-dimensional image patterns, wherein if ambiguity exists in segmenting a unit pattern including a character from the image patterns, character recognition is not made compulsively, but a plurality of possible unit patterns are first established. Then, the various unit patterns are segmented, and each unit pattern is identified to be a partial pattern, linked patterns, etc., so that each chara...

For time-sequential segment tracing, also of moving regions, a method of segmenting time-sequential images of a picture signal, in which, within an image, the image is split up into regions during its segmentation, and in which adjacent pixels having similar luminance and/or chrominance values are associated with a region is characterized in that it is attempted in time-sequential images to retrace regions of an image I.sub.n in a subsequent image I.sub.n+1 by performing a motion estimation of t...

The memory array circuit this invention provides connection of segmented bitlines to bitline decoding circuitry while, at the same time, providing connection of combined wordlines wordline decoding circuitry. The segmentation and decoding connections permit faster speed of operation with minimal or no area penalty. The area penalty is avoided by driving common wordlines in each of the segments, effectively increasing the wordline pitch at the wordline decoder, while at the same time decreasing t...
