Publication number: 20240135675Abstract: Detecting fine-grained similarity in image includes determining a core area of a search image by generating an image salient map from a plurality of layers of the search image and determining a connected area based on the image salient map. Feature descriptors are generated from the core area of the search image. A plurality of capsule vectors are generated from different ones of a plurality of keypoints of the feature descriptors. Capsule vectors of the search image are compared with capsule vectors of each image of the dataset to generate a top-K matrix. Similarity scores for the top-K matrix are calculated. One or more image of the dataset having fine-grained similarity with the search image are selected based a bundled similarity score for each image of the dataset. The bundled similarity score is a summation of the similarity scores of the image.Type: ApplicationFiled: October 23, 2022Publication date: April 25, 2024Inventors: Fei Wang, Xue Ping Liu, Dan Zhang, Yun Jing Zhao, Kun Yan Yin, Zhi Xing Peng, Jian Long Sun
