摘要： A system for automatically detecting the presence of contaminants in samples. The system includes a microscope, controllable stage positioner for holding slides under the microscope, a computer for controlling the stage positioner and a digital camera to capture images through the microscope. The system scans microscope views of regions of a slide sample and provides the digital images to the computer. Image processing routines stored in the computer analyze the digital images and determine whether these images may contain certain contaminants by comparing the characteristics of the objects in the image with the known characteristics of the contaminants. The system also contemplates a method for automatically determining the presence of contaminants in samples including the steps of providing a microscope slide containing a sample, obtaining a plurality of digital microscope images of the sample, storing the digital images in a computer, automatically comparing characteristics of each digital image to characteristics of known contaminants and storing the results of the comparison.

摘要： The present system and apparatus uses image processing to recognize object size within a scene. The system includes novel image processing apparatus and methods to segment one or more object images from a background image of the scene. A processed image (that can be used to characterize size features) of the object(s) is then compared to stored reference images. The object size is recognized when a match occurs. The system can recognize object sizes independent of number of objects present and the objects may be touching each other and overlapping. The system can be trained to recognize object sizes that it was not originally programmed to recognize.

摘要： The invention automatically inspects the bond of a wire to a contact pad on a semiconductor chip. The apparatus includes a movable platform for holding semiconductor chips situated in lead frames; a video camera for sensing images; illumination means for illuminating a chip in a lead frame; an image processor to digitize and analyze the images; a bonding mechanism; and a host controller electronically connected to bonding mechanism, movable platform, video camera, and image processor. Image processor locates a bond on a pad in a digitized image and provides a first nominal center of ball bond image. The invention aligns the center of a polar coordinate transform image having one or more segments with the nominal center of ball bond image and evaluates ball bond image using the polar coordinate transform image to create a polar projection histogram array and store it. An edge filter is applied to histogram array to detect peaks and store their number and values. Polar coordinate transform image is aligned with a next nominal ball center location until a predetermined number of potential ball center locations is exhausted. The maximum peak in the list of stored peaks is selected as the radius of bond from which the size and position of bond is computed and reported to host controller for further action.

摘要： A side-by-side x-ray detector provides dual energy measurements in a scanned configuration where high and low energy detector elements are interspersed. Alternating high and low energy detector elements in both row and column allows for interpolation and time and space providing virtual measurements at identical times and locations reducing image artifacts and errors caused by edges in the image. The resulting detector may be suitable for a variety of imaging applications including medical densitometry and baggage scanning.

摘要： Input image data define an input image that shows a perimeter relationship representation, such as a Venn diagram or statechart. The representation includes a perimeters feature that satisfies a constraint on perimeters. The constraint can include a perimeter size criterion that distinguishes perimeters from labels. Or the constraint can include an enclosing perimeter criterion requiring a connected component within each perimeter and a perimeter label criterion requiring a label for each perimeter. The constraint can also include an empty perimeter criterion to distinguish empty perimeters from labels. The input image data are used to obtain perimeters data indicating parts of the input image that satisfy the constraint. The perimeters data are used to obtain relationship data indicating a relationship between distinctions represented by the perimeters. The relationship data can be used to obtain output image data defining an output image that includes precisely formed version of the representation or another graphical representation of the relationship, such as a table. The table can include a set label at the head of each row and an element label at the head of each column, with a bullet in a space in a row and column if the row's set includes the column's element.

摘要： The present invention involves a method of deriving the height and width of a graphic image from raw graphical image data stored in a computer system. It includes commencing execution of a height-width derivation program in the computer system and, at least once, operating the height-width derivation program to perform a series of steps. These include calculating the area of the image size, e.g. using the total number of bytes, and calculating the square root of the area to obtain a first value, and then determining by assumption a first assumed width and a first assumed height. For example, these assumptions may be achieved by calculating one half of the first value to obtain a first assumed width value and dividing the area by the first assumed width value to obtain a first assumed height value. Next, the first assumed height value and first assumed width value are rounded to the nearest whole number, further adjusting said values by predetermined increments and the resulting adjusted values are multiplied until their product produces the closest value equal to the area of the image size to obtain a second assumed height value and a second assumed width value. The method also involves a series of iterations to determine error indexes for various altered assumed values and finding the values with the lowest error index.

摘要： During a cardiac cine examination, a multiplicity of imaging sequences, each about 20 msec long, are applied following the R-wave. Each imaging sequence includes a saturation portion in which a bi-modal pre-saturation pulse (38) and a spoiler gradient (56) are applied. The bi-modal RF pulse has a relatively low tip angle, about 50.degree., but is repeated sufficiently often that blood in regions (30a, 30b) parallel to a selected slice (32) are driven toward saturation. Each imaging sequence further includes a gradient echo or other conventional imaging sequence during an imaging portion to generate magnetic resonance data (60). Each imaging sequence is repeated twice for each temporal interval with the same phase encoding, but once with the relative phase of the signal in the slice and the relative phase of the signals from within the pair of regions (30a, 30b) reversed. These two signals are combined such that the signals from within the slice add and the signals from with the pair of regions subtract. Signals corresponding to the same temporal interval after the R-wave with each of a multiplicity of phase encodings are reconstructed (82) into an image representations (84) for display on a video monitor (96).

摘要： A printed pattern is provided with a wiring pattern having a land and a through hole surrounded by the land. The wiring pattern and the through hole are read by a photoelectric image sensor to obtain a pattern image and a hole image, respectively. A pattern gauge image is defined by the pattern image, and a hole gauge image having a ring-like shape is obtained from the hole image. A logical product between the inversion image of the pattern gauge image and the hole gauge signal provides a protrusion region image. Since the hole gauge image has an isotropic contour, the minimum annular width of the land is detected, independent of the direction in which the through hole is deviated from the land.
