It then encodes the angle of a tangent line segment within each cell (when present) at the boundary of objects in the view. It determines rate-of-curvature of the boundary to develop a linear signature for the object. The system breaks the linear signature into segments that can be normalized to be constant regardless of the scale of the image. It then generates identification numbers to identify the object through a mathematics process. The system utilizes pipeline processing to the point where the results are applied to a microprocessor. The microprocessor analyzes a stored image field of view in encoded format to determine object perimeter cell locations (a chaining process). It then traces this perimeter addressing the stored image field to recover processed differential angles and to control the development of a linear signature sequence. The mathematics process performed creates a first number representing the length of straight segments and creates a second number representing the degree of curvature of curved segments. The combination of the two numbers provides a high probability of unique identification of an object. The numbers are compared with established numbers of a template for identification of an object. A unique feature number of an object is established for the template. This feature is located on the chained object by segment comparison and the relative angular orientation, compared to the template orientation, is then determined. | 01-22-2009 |

20160104299 | REFERENCE BASED SIZING - Techniques for determining the dimensions of an object. The user of a smartphone snaps a digital photograph which includes both a reference item and the object. A processor then determines the object dimensions by analyzing the digital photo to determine the boundaries of the object and the reference item. From this boundary information, the dimensions of the object can be estimated without further interaction from the user. In optional aspects, the object boundaries can be used to identify the type of object against a database of objects. The object type may be taken into account when presenting the measured dimensions. For example, in a case where the object is recognized as being a pair of women's slacks, the resulting dimensions may be presented as a list of typical dimensions for such a garment including waist, hips, front rise, inseam, leg opening, etc. | 04-14-2016 |
20160110599 | Document Classification with Prominent Objects - Systems and methods classify unknown documents in a group or not with reference document(s). Documents get scanned into digital images. Applying edge detection allows the detection of contours defining pluralities of image objects. The contours are approximated to a nearest polygon.

Comparing the collection of features to those of an unknown image determine or not inclusion of the unknown with the reference(s). Embodiments typify collections of features, classification acceptance or not, application of algorithms, and imaging devices with scanners, to name a few. | 04-21-2016 |

20160379057 | DETERMINING NATIVE RESOLUTIONS OF VIDEO SEQUENCES - In one embodiment of the present invention, a native resolution analyzer generates a log-magnitude spectrum that elucidates sampling operations that have been performed on a scene. In operation, the native resolution analyzer performs a transform operation of a color component associated with a frame included in the scene to generate a frame spectrum. The native resolution analyzer then normalizes the magnitudes associated with the frame spectrum and logarithmically scales the normalized magnitudes to create a log-magnitude frame spectrum. This two dimensional log-magnitude frame spectrum serves as a frequency signature for the frame. More specifically, patterns in the log-magnitude spectrum reflect re-sampling operations, such as a down-sampling and subsequent up-sampling, that may have been performed on the frame. By analyzing the log-magnitude spectrum, discrepancies between the display resolution of the scene and the lowest resolution with which the scene has been processed may be detected in an automated fashion. | 12-29-2016 |
