| Number | Title | Issue Date |
| 6901171 | Methods and apparatuses for refining groupings of edge points that represent a contour in an image Methods and apparatuses are disclosed for refining groupings of edge points that represent contours in an image. The methods and apparatuses decrease data dispersion and data quantization effects. The methods and apparatuses are particularly useful for accurate and ... | 05/31/2005 |
| 6898333 | Methods and apparatus for determining the orientation of an object in an image A method and an apparatus are disclosed for finding an orientation of an object from the image of the object through the generation of, and subsequent evaluation of, at least a portion of a frequency response of the image. The orientation of the object can be used i... | 05/24/2005 |
| 6813377 | Methods and apparatuses for generating a model of an object from an image of the object A method and an apparatus are disclosed for generating a model of an object from an image of the object. First, an orientation of the object in the image is determined through the generation of, and subsequent evaluation of, at least a portion of a frequency respons... | 11/02/2004 |
| 6801649 | Method and apparatus for determining a reference point of a bottle bottom in an image An efficient and reliable method and apparatus is disclosed that finds a reference point of an object profile within an image when the object is of an unknown size. The object profile is modeled using a synthetic labeled-projection model, which in conjunction with t... | 10/05/2004 |
| 6798515 | Method for calculating a scale relationship for an imaging system The disclosed methods and apparatuses leverage a known value of a characteristic of an object to partially calibrate an imaging system “on-the-fly”, and minimize, if not eliminate, the need for a separate calibration image(s). Specifically, the scale relationshi... | 09/28/2004 |
| 6714679 | Boundary analyzer A method and apparatus are disclosed for analyzing a boundary of an object. An embodiment for determining defects of a boundary to sub-pixel precision and an embodiment for fast correlation scoring are disclosed. The boundary is analyzed by matching a first boundary... | 03/30/2004 |
| 6714670 | Methods and apparatuses to determine the state of elements A methods and apparatuses are disclosed for determining the state of elements in an image. The elements can be arranged in any regular pattern, such as a matrix of LCD display elements. The state of the elements is determined by extracting a characteristic of the el... | 03/30/2004 |
| 6697535 | Method for refining a parameter of a contour in an image Methods and apparatuses are disclosed for refining groupings of edge points that represent contours in an image. The methods and apparatuses decrease data dispersion and data quantization effects. The methods and apparatuses are particularly useful for ac... | 02/24/2004 |
| 6647132 | Methods and apparatuses for identifying regions of similar texture in an image Methods and apparatuses are disclosed for identifying regions of similar texture in an image. The areas of similar texture include areas conventionally thought of as similar texture regions as well as areas of more varied texture that are treated as regio... | 11/11/2003 |
| 6614926 | Methods and apparatuses for generating from an image a model of an object The invention provides methods and apparatuses for generating from an image of an object a model of the object, when the object contains similar features. First, the invention finds the similar features. The similar features are found by searching portion... | 09/02/2003 |
| 6577775 | Methods and apparatuses for normalizing the intensity of an image A methods and apparatuses are disclosed for determining the state of elements in an image. The elements can be arranged in any regular pattern, such as a matrix of LCD display elements. The state of the elements is determined by extracting a characteristi... | 06/10/2003 |
| 6490375 | Methods for finding peaks in a characteristic surface of an image An efficient and reliable method that identifies possible reference sites in an image is disclosed. The method emphasizes customizing the identification of reference sites for each application by providing for initialization of various parameters, such as... | 12/03/2002 |
| 6327393 | Method and apparatus to transform a region within a digital image using a deformable window A method and apparatus is provided for intuitively, graphically parameterizing a region of an input image to be processed by a machine-vision vision system, the region being defined by a deformable window, where the window is deformed by a user using a po... | 12/04/2001 |
| 6317513 | Method and apparatus for inspecting solder paste using geometric constraints Inspection of solder paste on a printed circuit board using a before printing image (pre-application image) to normalize an after printing image (post-application image) of the printed circuit board. Existing lighting and optics used for alignment of the ... | 11/13/2001 |
