Abstract: A method to improve the efficacy of optical character recognition (OCR) includes scanning an electronically stored representation of a whole or partial document, identifying an image having text in the electronically stored representation of a whole or partial document, identifying the text within the image, and generating a plurality of bounding boxes around the identified text using blob detection. The method also includes grouping together certain text bounding boxes of the plurality of text bounding boxes that are vertically aligned with each other to generate a plurality of aligned text bounding boxes and performing OCR on the aligned text bounding boxes to generate a plurality of OCR groups of text. In addition, the method includes generating a resultant representation of a whole or partial document electronically using the plurality of OCR groups of text and saving the resultant representation of a whole or partial document electronically.

Abstract: A method of detecting concealed objects using a thermal imager includes obtaining an output comprising a plurality of pixels representing a person, analyzing each pixel matching a contour of the person and excluding any pixel within a blob bounding box of the person, and determining whether a pixel address is represented in a pixel map. In addition, the method includes comparing a value of each remaining pixel to an allowable minimum threshold value representing a lower pre-defined body temperature, and comparing the value of each remaining pixel greater than or equal to the allowable minimum threshold value to an upper allowable threshold value representing an upper pre-defined body temperature. The method also includes excluding any of the remaining pixels within a range between the lower and upper pre-defined body temperatures to define final set of pixels and calculating a pixel difference to indicate a severity of the difference.

Abstract: A system to preprocess images to increase accuracy of optical character recognition (OCR) includes a processor, and a memory coupled to the processor. The processor is configured to scan an electronically stored representation of a whole or partial document, identify an image in the electronically stored representation, and recognize row-based text within the electronically stored representation. In addition, the processor is configured to align the row-based text vertically, generate a resultant electronically stored representation of the whole or partial document having the row-based text aligned, and save the resultant electronically stored representation for subsequent OCR processing. The electronically stored representation of the whole or partial document may contain at least one image having a JPG, TIF, GIF, PNG, or BMP, type of format.

Abstract: A real-time threat detection system incorporating a plurality of sensors adapted to detect radiation across the majority of the electromagnetic spectrum. The system also includes an aided or automatic target recognition module which compares the data from the sensors against known radiation signatures and issues an alert when an anomalous signature is detected. The system further includes an operator station which displays sensor information allowing the operator to intervene. The sensors detect radiation which is normally emitted by persons or other bodies and display areas to the operator where normal emissions are blocked.

In addition, the software 3-D avatar is dimmed, modified with text, graphics, colors, textures, opacity, transparency, or any combination thereof, when no individuals are detected in the scanning area.

Abstract: A system and method for manipulating computer data using a new GUI element is disclosed. In a particular embodiment, the new GUI element is a composite of a traditional GUI button control and a traditional GUI slider control. In one embodiment, a composite slidable button control appears and functions similar to a traditional button control on the GUI.

During the slider adjustment phase, the composite control can optionally overlap other GUI elements realizing a more compact and efficient GUI appearance. In another embodiment, a composite clickable slider control appears and functions similar to a traditional slider control on the GUI.
