摘要:
A combination of inter-frame and intra-frame and sequential classification methods provide for robust and flexible object classification. Intra-frame classification determines the object type based on features extracted from a single image. Inter-frame classification determines object types based on the features extracted from several sequential frames. A sequential classification combines the results of the inter- and intra-frame classifications over a sequence of images.
摘要:
A method for motion detection includes capturing a plurality of frame images. The plurality of frame images is preprocessed. A first background reference is generated based on a first subset of the plurality of frame images. A second background reference is generated based on a second subset of the plurality of frame images, wherein the second subset of the plurality of frame images is a subset of the first subset of the plurality of frame images. A first motion result is generated based on the first background reference and a second motion result is generated based on the second background reference. The first motion result and the second motion result are combined to generate a combined result. Object motion is detected based on the combined result.
