摘要： An apparatus and method for stabilizing image frames in a video data stream. A weighted average or centroid of the intensity or hue associated with pixels vs. the horizontal and vertical position of each pixel is calculated for a reference frame in the video data stream. A corresponding centroid is calculated for a subsequent frame in the stream. This image frame is then translated so that the centroid of the subsequent frame and the centroid of the reference frame coincide, reducing artifacts from shaking of the video capture device. Alternatively, the video stream frames may be divided into tiles and centroids calculated for each tile. The centroids of the tiles of a subsequent frame are curve fit to the centroids of tiles in a reference frame. An affine transform is then performed on the subsequent frame to reduce artifacts in the image from movements of the video capture device.

摘要： A computer-implemented method of processing digital input image data containing haze and having a plurality of color channels including at least a blue channel, to generate output image data having reduced haze, includes receiving in a first computer-implemented process, digital input image data, and generating, in a second computer-implemented process, digital output image data based on the digital input image data using an estimated transmission vector for the digital input image data. The estimated transmission vector is substantially equal to an inverse blue channel of the digital input image data, and the digital output image data contains less haze than the digital input image data. The method also includes outputting the digital output image data via an output device.

摘要： An apparatus and method for preparing a composite image from a video data stream and for identifying changed features in two composite images. Frames from the video data stream are transformed to a projected 2D image, aligned with adjacent frames and overlapping areas are averaged to provide a higher apparent resolution. The composite image can be stored in real-time. As a second composite image is prepared of the same location at a later time, portions of the second image can be compared to corresponding portions of the stored image after the intensities of the images are equalized. Image areas whose absolute difference exceeds a threshold are again intensity equalized. Areas that are again above threshold can be flagged for further scrutiny, either by a human or by a machine that performs object recognition. In this way, composite video images of a scene can be prepared and compared in real-time.

摘要： A system to parse both telemetry data and corresponding encoded video data wherein the telemetry and video data are subsequently synchronized based upon temporal information, such as a time stamp. The telemetry data and the video data are originally unsynchronized and the data for each is acquired by a separate device. The acquiring devices may be located within or attached to an aerial vehicle. The system receives the telemetry data and the encoded video data and outputs a series of synchronized video images with telemetry data. Thus, telemetry information is associated with each video image. The telemetry data may be acquired at a different rate than the video data. As a result, telemetry data may be interpolated or extrapolated to correspond to each video image. The present system operates in real-time, thus data acquired from aerial vehicles can be displayed on a map.

摘要： A method of transforming an input image from a hemispherical source to an output image in rectilinear coordinates is disclosed. The method includes receiving data representative of an input image originating from a hemispherical camera and having a size defined by an input image height and an input image width. Once the data is received, an output image width and output image height representative of a size of a rectilinear output image is calculated based on the size of the input image. A rectilinear output image is then generated by mapping input image pixels to locations within the width and height of the output image, without reference to the optical characteristics of the hemispherical camera.

摘要： A method and system for estimating the average speed of a moving object based on an attribute of the moving object present within the captured image data is disclosed. A plurality of images of the moving object are recorded using an image sensor that senses the ambient light or other electromagnetic radiation reflected or emitted by the moving object. Each image is captured at a different capture time. The image sensor is preferably located at a fixed or substantially fixed location when imaging the moving object. An area of interest of the moving object is located within the image data of the first image. An attribute of the moving object is then calculated for the first image. For at least a second image, the same attribute is calculated for the same area of interest of the moving object. The attribute calculations for the first and at least second images are then used to determine the average speed of the moving object. The attribute may be the cross-sectional area of the area of interest of the moving object.
