Use of network traffic analysis gopacket library in go
1. Preface Recently, the author wants to learn how to use go to construct tcp data packets. This involves the use of the gopacket library, so here are some learning records about the gopacket library. 2. Introduction gopacket is a network packet processing library in the Go language. It provides a convenient API to read, […]
Based on Segment-and-Track Anything and ProPainter to achieve one-click target removal and one-click watermark removal from videos
1. ProPainter 1. Introduction to the algorithm ProPainter is a video repair tool developed by the S-Lab team of Nanyang Technological University in Singapore. It combines the advantages of image and feature restoration with efficient Transformer technology, aiming to provide high-quality video restoration effects while maintaining high efficiency. ProPainter includes the following features: Object Removal: […]
Wash away all the brilliance without applying makeup, artificial intelligence AI removes image and video watermarks based on ProPainter technology (Python3.10)
Video and picture restoration technology is a challenging AI vision task that involves filling in missing or damaged areas in a video or picture sequence while maintaining spatial and temporal coherence. This technology is widely used in video completion, object removal, video recovery and other fields. In recent years, two prominent solutions have emerged in […]

Implementation of propagation characteristics of spring thing source code reading
The Spring transaction propagation feature refers to how transactions are managed between multiple transaction operations. The Spring framework provides different transaction propagation features for defining transaction boundaries and isolation levels. Let’s first review what types of spring transaction propagation there are Propagation type PROPAGATION_REQUIRED (default): If a transaction currently exists, join the transaction; if there […]
