摘要:
A moving object detection method according to an embodiment includes evaluating an average value (Tave), instead of a median value (T6), of pixel values (T1 to T8) at the same pixel positions across multiple superposed images. A threshold value (Tth) obtained by multiplying the average value (Tave) by a predetermined number is employed to distinguish space debris from an object which emits light at a higher luminance than the space debris. In order to detect the space debris accurately, an average value (Tave') of the pixel values (T1 to T4 and T6 to T8) that are equal to or less than the threshold (Tth) is employed as an evaluation value for the space debris detection.

The method comprises the steps of, successively for each image (2) following a preceding image (1), - based on a map of motion vectors that corresponds to the motion from said preceding image (1) toward said following image (2), building a pixel mask for said following image (2), - applying said pixel mask to the corresponding following image (2) in order to obtain a corresponding masked image that samples the pixels of said following image (2). The application of this method to color clustering allows the iterative update of the colors clusters with limited computer resources.
摘要:
An image processing device includes an evaluation value calculation section (321), an estimated noise amount acquisition section (322), a determination section (324), and a noise reduction processing section (325). The evaluation value calculation section (321) calculates an evaluation value that is used to determine whether or not an inter-frame state of an object within a captured image is a stationary state. The estimated noise amount acquisition section (322) acquires an estimated noise amount of the captured image. The determination section (324) determines whether or not the inter-frame state of the object is the stationary state based on the evaluation value and the estimated noise amount. The noise reduction processing section (325) performs a first noise reduction process (time-direction noise reduction process) on the captured image when it has been determined that the inter-frame state of the object is the stationary state, and performs a second noise reduction process that includes at least a spatial-direction noise reduction process on the captured image when it has been determined that the inter-frame state of the object is not the stationary state.

Disclosed are methods, systems, computer readable media and other implementations, including a method that includes determining, from image data captured by a plurality of cameras, motion data for multiple moving objects, and presenting, on a global image representative of areas monitored by the plurality of cameras, graphical indications of the determined motion data for the multiple objects at positions on the global image corresponding to geographic locations of the multiple moving objects. The method further includes presenting captured image data from one of the plurality of cameras in response to selection, based on the graphical indications presented on the global image, of an area of the global image presenting at least one of the graphical indications for at least one of the multiple moving objects captured by the one of the plurality of cameras.
