Abstract: A video processor for recognizing gestures, including a video camera for capturing photographs of a region within the camera's field of view, in real-time, an image processor coupled with the video camera for detecting a plurality of hand gestures from the photographs captured by the video camera, and a controller coupled with the image processor, wherein the controller can be in a dormant mode or an active mode, and wherein the controller transitions from dormant mode to active mode when the image processor detects a progression of two states within the captured photographs, the two states being (i) a closed fist and (ii) an open hand, and wherein the controller performs a programmed responsive action to an electronic device based on the hand gestures detected by the image processor when the controller is in active mode. A method and a computer-readable storage medium are also described and claimed.

Abstract: A method for image processing in a computerized system reduces the amount of memory required for image processing and produces a layered effect which permits complex manipulation such as scaling and rotation without long delay, while allowing earlier versions of the visual image to be recalled. The method involves pre-processing, image editing and raster image processing.

Abstract: Embodiments of the present invention are directed to a method and apparatus for probabilistic image analysis. In one embodiment, an image is normalized and filtered. A determination is made regarding the likelihood of the image randomly matching characteristics of the reference image. If the likelihood is smaller than a threshold, the system determines that the image and the reference image match. In one embodiment, the likelihood is determined by using patches of skin in the images. In one embodiment, the likelihood is derived from the coherence of the optical flow computed between the two images. In one embodiment, the image is partitioned into a plurality of pixel regions. A pixel region in one image is mapped to a best-fit region in the other image. A neighbor region of the pixel region is mapped to a best-fit pixel region in the other image.

Abstract: A vision-based operating system is provided in which a computer-based system accepts visual inputs and takes appropriate actions in a wide variety of environments. One environment is a security environment in which the vision-based operating system acquires an image of a face and determines, with an arbitrarily small probability of a false positive, whether the face is of a person who is authorized to enter the environment.

Abstract: A method for transforming a first image defined by a first multi-dimensional color space (RGB) into second image defined by a second multi-dimensional color space (CMYK). The method computes the transformation using information derived from a previous transformation of said second image into said first image. The method then minimizes the error produced while transforming the second image back into the first image. As such, an image editing system can display on a video monitor an image that is defined in one multi-dimensional color space (RGB), print using a printer that prints images using a second multi-dimensional color space (CMYK) and edit an image using any multi-dimensional color space (either RGB or CMYK) that facilitates rapid and accurate image editing.

Abstract: A method for transforming a first image defined by a first multi-dimensional color space (RGB) into second image defined by a second multi-dimensional color space (CKX). The method computes the transformation using information derived from a previous transformation of said second image into said first image.

Abstract: A method for non-destructive, selectably reversible image compositing, including providing a displayed image including at least a region of an original image, modifying the displayed image to produce a modified displayed image, and producing a modified image file including at least the displayed image and not including the modified displayed image and also including resolution independent parameters operative for modifying the displayed image to produce the modified displayed image. A system is also described and claimed.

Abstract: An image processing system and a concomitant method for rapid image processing. The system generates special image format containing a plurality of subimages. When an image is edited, the system uses the information in the subimages to calculate a depiction of the image on the display appropriate to display resolution, given the current pan and zoom. Image alterations are stored within a computer file as an expression tree. Each node in the expression tree defines a particular editing operation that resulted in modifications to the image. To display the image upon a computer monitor display, the expression tree defining the alterations is evaluated to form a composite output image having a resolution appropriate to display an accurate rendition of the edited image. Once edited, the output image can be printed on a high resolution printer by combining the expression tree with a full resolution image to produce a high resolution output image.
