Embodiment 1
[0032] First, refer to figure 1 An example electronic system 100 for implementing the image-based method, device and electronic system for counting target objects according to an embodiment of the present invention will be described.
[0033] like figure 1 Shown is a schematic structural diagram of an electronic system, an electronic system 100 includes one or more processing devices 102, one or more storage devices 104, an input device 106, an output device 108, and one or more video capture devices 110, these components The interconnections are via bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structures of the electronic system 100 shown are exemplary rather than limiting, and the electronic system may also have other components and structures as required.
[0034]The processing device 102 may be a smart terminal, or a device including a central processing unit (CPU) or other forms of processin...
Embodiment 2
[0041] This embodiment provides a method for processing video data, which improves the traditional task model for convolution calculation, such as figure 2 A flow chart of a processing method for video data shown, the processing method for video data includes the following steps:
[0042] Step S202, dividing the target video into key frames and normal frames.
[0043] The target video refers to the video used for convolution calculation. The format of the target video is not limited, as long as different video frames can be extracted from the target video. The target video includes several images, each of which is a video frame, and these video frames are divided into key frames and normal frames.
[0044] First, the initial video frame of the target video is divided into key frames, and then the remaining key frames are determined. Each key frame must be different from the previous key frame, that is, each key frame needs to continue the previous key frame with a differenc...
Embodiment 3
[0056] This embodiment provides another method for processing video data. This method improves the traditional task model for performing convolution calculations. The embodiment focuses on describing the specific process of performing convolution on the L+1th convolutional layer. In this embodiment, the task model includes multiple convolutional layers, and the video data is convoluted through the convolutional layers, such as image 3 Shown is a flow chart for convolution of the L+1th layer convolutional layer, the method for convolution of the L+1th layer convolutional layer includes the following steps:
[0057] Step S302, obtaining input information; the input information includes: the key features corresponding to the key frames output by the L-th convolutional layer and the common features corresponding to the ordinary frames; wherein, the key features in the input information of the first convolutional layer are the key Frames, common features are common frames.
