Abstract: The present disclosure provides an image processing method, apparatus, and device, and a storage medium. The method includes determining, in response to receiving a preset identification operation triggered for a capturing frame on a capturing page, a target image having image clarity meeting a preset clarity condition based on the capturing frame on the capturing page. Then, the target image is transmitted to an image identification server for image identifying. Thus, the image processing method provided in the embodiments of the present disclosure can determine a target image having image clarity meeting a preset clarity condition first before image identification and allow an image identification server to perform identification based on the target image which meets the preset clarity condition, thereby the accuracy of image identification can be improved.

Abstract: A strain relief clamp (100), which has a first body part (110) and a second body part (120) creating a passage (160) for clamping cables upon the two body parts securely attached together by using locking mechanisms (105,106). An individual locking mechanism (105) has a first plurality of teeth (115) protruded from the first body part (110), and a spring strip (130) formed with a second plurality of teeth (135). The second plurality of teeth (135) faces and engages with the first plurality of teeth (115) to lock the individual locking mechanism (105). The spring strip (130) is bendable, allowing a user to bend the spring strip (130) and subsequently cause the second plurality of teeth (135) to disengage from the first plurality of teeth (115) to release the individual locking mechanism (105). Tool-free release of the cables is achieved, offering the user convenience.
