Design And Implementation Of Short Video Advertisement Placement System Based On Rectangular Flat Objects

With the development of society and the improvement of technology,mobile Internet and smart devices are developing rapidly.Due to the large amount of information and short duration of short video,which conforms to the usage habits of users of all ages,short video applications emerge in endlessly and occupy a large number of user markets.The large number of users has created huge business opportunities,and the most important way for short video revenue is the placement of advertisements.However,the ad placements in traditional video websites are mostly patch ads and mid-roll ads,which seriously affect the user experience and are not suitable for short video application scenarios.Aiming at the shortcomings of traditional video advertisement placement technology,this paper designs and implements a short video advertisement placement system based on rectangular flat objects.For the rectangular flat objects appearing in short videos,semantic segmentation is used to segment the object positions.Finally,the rectangular advertisement picture is naturally integrated into the picture at that position to achieve a seamless advertisement placement effect.The main work of this paper is as follows:For the research of semantic segmentation technology in complex scenes,a semantic segmentation network based on context adaptive convolution and stripe pooling is proposed,which can effectively segment complex scenes and occluded objects.This network uses context-adaptive convolution kernels to generate context weight factors,and adds stripe pooling branches on the basis of Cac-Net for improvement,and further improves the segmentation performance of rectangular objects in complex scenes.The algorithm has achieved good accuracy on the public data set,which verifies the effectiveness of the algorithm.Aiming at the shortcomings of traditional video advertising and the rise of short videos,a short video advertisement placement system based on rectangular flat objects is designed.The entire system is composed of a mobile terminal and a server terminal.The mobile terminal includes a UI interaction layer and a transaction processing layer.The server side includes a business logic layer and a data access layer.The system realizes that the natural fusion of advertising pictures is maintained when the position of the rectangular object is blocked,and the advertisement is matched with the video content,which can further improve the user experience and advertising effect.Finally,the feasibility and effect of the system are tested.
