Abstract: The present disclosure discloses a defrosting control method, a central controller and a heating system. The defrosting control method comprises: heating fluid in a flow passage between an inlet and an outlet of a first heat source by a second heat source, at least in a part of process of defrosting by the first heat source; acquiring an operation parameter of the first heat source, wherein the operation parameter comprises a water outlet temperature and/or a water return temperature and/or an operation parameter of a compressor of the first heat source, comparing a current value of the acquired operation parameter with a preset range of the operation parameter, and adjusting a heat exchange amount between the second heat source and the fluid when the acquired current value is within the preset range.

Abstract: 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.

Abstract: One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to detecting a closed ring in a three-dimensional (3D) point cloud via cycle basis. A system can comprise a memory configured to store computer executable components; and a processor configured to execute the computer executable components stored in the memory, wherein the computer executable components can comprise a filtering component that can filter a first undirected graph of a three-dimensional (3D) point cloud, by eliminating one or more edges of the first undirected graph that are longer than an adaptive threshold, wherein filtering the first undirected graph can produce a second undirected graph; and a detection component that can detect a minimum cycle basis of the second undirected graph to determine a cycle path that can traverse an irregular annular shape that is represented by the 3D point cloud.

Abstract: A computer-implemented method, system and computer program product for improving accuracy of a vision model. Images of an object with a first set of perspectives are received from a dataset used to train the vision model. A three-dimensional model of the object is then generated using the images of the object from the dataset. Using the three-dimensional model of the object, images of the object with a second set of perspectives are obtained. For example, the second set of perspectives may include different perspectives than the perspectives of the object from the images contained in the dataset. The dataset used to train the vision model may then be augmented with such images of the object with a second set of perspectives. In this manner, the dataset used to train the vision model includes a greater number of perspectives of the object thereby improving the accuracy of the vision model.

Abstract: A computer system, computer product, and method for accessing a secure store, which includes receiving a request to access a secure store, checking the file path of the request to make sure it exists in the secure store, verifying security parameters from the process at the file system filter layer, saving the PID of the process by the file system filter layer, comparing the saved PID to the process's PID, and allowing the process to access the path in the secure store specified in the request.
