Abstract: A method and an apparatus for recognizing a key identifier in a video, a device and a storage medium are disclosed. The method includes: extracting a plurality of key frames from the video; generating a mask of the key identifier by using a difference between the plurality of key frames; determining, in video frames of the video, a key identifier area image by using the mask; and recognizing the key identifier area image to obtain a key identifier category included in the video.

Abstract: A filter debugging method, a device, an electronic apparatus and a readable storage medium are provided. The filter debugging method includes: step S1: inputting a current hole parameter and a current index value of a filter into a policy network which is pre-trained; step S2: determining, by the policy network, a target hole to be polished of the filter, according to the current hole parameter and the current index value of the filter; step S3: controlling a mechanical arm to polish the target hole of the filter; and step S4: determining whether the filter is qualified according to an index value of the polished filter; in a case that the filter is qualified, ending a process including the steps S1 to S4; in a case that the filter is unqualified, performing the steps S1 to S4 circularly until the filter is qualified.
