Abstract: Embodiments of this disclosure disclose an image data processing method and apparatus. The processing method includes: processing a first image and a second image by using a first neural network to obtain a homography matrix; determining a mapped image feature of a first image feature based on the homography matrix; fusing the mapped image feature and a second image feature to obtain a fused image feature; and processing the fused image feature by using a second neural network to obtain a first pixel height-to-depth ratio of the second image. In the embodiments of this disclosure, a dense and accurate pixel height-to-depth ratio can be obtained, thereby facilitating 3D scene modeling.

Abstract: A high temperature and high salinity-resistant complementarily rigid-flexible plugging agent, a method for preparing the same, and a water-based drilling fluid and a use thereof.

Abstract: An application acceleration method includes identifying a data packet to be transmitted by an application running on a mobile terminal as a data packet to be accelerated to an application server, and determining network communication qualities of a first network transmission path to an access node via a wireless LAN communication network and a second network transmission path to the access node via a mobile network. The method further includes selecting a network transmission path based on network communication quality from the first network transmission path and the second network transmission path, and transmitting the data packet to the access node via the selected network transmission path such that the access node transmits the data packet to the application server through the network acceleration channel. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

Abstract: Provided is a carwash machine. The carwash machine includes: a steam generator and a spray gun connected to the steam generator.
