Embodiment Construction
[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] see figure 2 , in one embodiment, a classifier-based object detection method is provided. The method includes:
[0047] In step 202, an image pyramid is established from the original image according to a preset scaling factor.
[0048] Specifically, in the field of video surveillance, images are captured by an image sensing device, which may be based on CMOS or CCD technology, and the original image may be the image directly captured by the image sensing device or after grayscale, etc. The image processed by means is not limited here. For the process of establishing an image pyramid fro...
