The proposed approach effectively mitigates accuracy constraints caused by image noise and shadow effects from uneven illumination. The methodology comprises three key phases: Applying an optimized bilateral filtering algorithm to perform noise reduction on grayscale images, producing denoised images; Segmenting micro-operation targets using the refined Otsu algorithm on these denoised images to obtain initial segmentation results; Directly applying the final segmentation result when meeting predefined criteria, or conducting iterative segmentation through the enhanced edge operator and Otsu algorithm if necessary.

Abstract: This application relates to the field of communication technologies, and provides a communication method and apparatus. In the method, before receiving a random access preamble from a terminal device, a network device sends a random access response message to the terminal device. For different terminal devices, the network device may respectively indicate different timing advances by using different random access response messages, to stagger time at which the different terminal devices send messages (for example, Msg3) to the network device. This reduces mutual interference between the messages sent by the different terminal devices, and reduces a probability that the network device fails to receive the message of the terminal device, to help improve an access success rate of the terminal device.
