Embodiment 1
[0026] refer to figure 1 , which is a schematic flow chart of the moving target detection method provided in Embodiment 1 of the present application, the method includes the following steps:
[0027] Step 101: extract the grayscale feature, direction feature, optical flow feature of the current frame image and the inter-frame difference feature of the current frame image in the specified image set, wherein the specified image set is an image composed of consecutive frame images containing the current frame image gather.
[0028] Wherein, in one embodiment, grayscale features, direction features, optical flow features and inter-frame difference features can be extracted according to the following methods:
[0029] (1) Grayscale features:
[0030] Assuming that the red, green and blue channels of the current frame image are r(t), g(t), and b(t) respectively; then the grayscale feature of the image can be expressed as shown in formula (1):
[0031] I(t)=(r(t)+g(t)+b(t)) / 3 (1) ...
Embodiment 2
[0101] Based on the same inventive concept, the embodiment of the present application also provides a moving object detection device. The principle and beneficial effects of the device are similar to those described in the above method embodiments, and will not be repeated here.
[0102] Such as figure 2 Shown is a schematic structural diagram of the device, including:
[0103] The feature extraction module 201 is used to extract the grayscale feature, direction feature, optical flow feature of the current frame image and the inter-frame difference feature of the current frame image in the specified image set, wherein the specified image set is a continuous frame containing the current frame image An image collection composed of images;
[0104] A feature weight acquisition module 202, configured to acquire various corresponding weights of grayscale features, directional features, optical flow features, and inter-frame difference features;
[0105] The feature fusion module...
