Merchants have manually sorted and uploaded a large number of clothing images to make it easy for users to shop for clothing online, which consumes a huge amount of labor costs. Such problems can be improved through deep learning related algorithms. However, the conventional deep learning model has a huge amount of computation, resulting in low efficiency of real-time detection of clothing, which limits its application field. Aiming at these theoretical and practical problems, this thesis studies the optimization of clothing image detection and label recognition methods based on deep learning. In view of the real problems of high computational load and slow instant response of existing clothing detection models. This thesis proposes a clothing detection model YOLOv4-GS based on a deep learning framework. Experiments show that compared with the model YOLOv4, this model has a great improvement in detection accuracy and model efficiency. This algorithm first uses the K-means++ clustering method to preprocess the initial dataset DeepFashion2. And construct the GS module based on the deep fusion of Ghost module and SimAM attention mechanism. Then use the GS module to reconstruct the YOLOv4 network to obtain the model YOLOv4-GS, which has higher efficiency and higher model accuracy.","PeriodicalId":344365,"journal":{"name":"2022 21st International Symposium on Distributed Computing and Applications for Business Engineering and Science (DCABES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123550387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it causes easily the inaccurate tracking when the scene is complex, for example, the object is seriously occluded, the color of the object is similar to that of the background, the background is dynamic, and the camera shakes or moves. Aiming at the above problems, a novel object tracking algorithm based on MSA and SURF (Speeded Up Robust Features) is proposed. Firstly, the object area in the current frame is determined by MSA, and secondly, SURF algorithm is used to match the feature points in the object area of initial frame with those in the object area of current frame, and finally, the coordinates of the center point in the object area of current frame are adjusted according to the matching results.

Therefore, SACS is proposed, whose pheromone matrix uses triplet sparse storage. In order to solve the problem of how to deal with the number of items of the initial allocated pheromone triplet and the new non-default pheromone update, this paper proposed the method based on the small fixed storage space with different replacement policies, those are, SACS-Max, SACS-Min, SACS-Rand.
