Abstract: A computer-implemented method of assessing whether a patent has a condition is provided, including generating a facial landmark on a received input video to define points associated with a region of interest on a face of the patient, defining a period of talking based respective positions of the defined points, during the period of talking, measuring pause frequency, repetitive pattern, and vocabulary variety, without determining or applying semantic information associated with the talking, to generate an aggregate score, and based on the aggregate score, generating a prediction of the patient having the condition associated with the aggregate score.

Abstract: A television signal substitution system that replaces known video segments such as advertisements with selected replacement advertisements. Fingerprint data of known advertisements can be stored in a fingerprint database. When new fingerprint data is available, the fingerprint data can be automatically or manually transmitted to subscribers. Various techniques can be used to identify advertisements based on the fingerprint data.

Abstract: A method and system for processing video signals is disclosed. The system receives a video signal, a first audio signal containing an annotation and a second audio signal containing environmental sounds corresponding to the video signal. In one embodiment the system generates searchable annotations corresponding to the video and second audio signals via the first audio signal.

Abstract: In some embodiments, the invention includes receiving a digital image including text and background. The method includes vector quantizing the digital image such that the digital image is divided into certain colors, and creating a text color histogram from a portion of the text and a first portion of the background. The method also includes creating at least one background color histogram from a second portion of the background, and creating a difference color histogram from a difference between the text color histogram and the at least one background color histogram, and wherein an estimated color of the text is derived from the difference color histogram. In other embodiments, the invention includes receiving a text object including bounding boxes of multiple frames of a video signal.

Abstract: In some embodiments, the invention includes a method for locating text in digital images. The method includes scaling a digital image into images of multiple resolutions and classifying whether pixels in the multiple resolutions are part of a text region. The method also includes integrating scales to create a scale integration saliency map and using the saliency map to create initial text bounding boxes through expanding the boxes from rectangles of pixels including at least one pixel to include groups of at least one pixel adjacent to the rectangles, wherein the groups have a particular relationship to a first threshold. The initial text bounding boxes are consolidated.
