Abstract: A method for aligning a text with a media material, an apparatus, and a storage medium are provided. The method includes: determining a set of anchor points in the text; performing following operations i) to v) repeatedly until all anchor points are removed from the set of anchor points or all media materials are removed from a set of media materials: i) ranking the anchor points in the set of anchor points, ii) selecting a target anchor point from the set of anchor points based on the ranked anchor points in the set, iii) determining, from the set of media materials, a media material matching a text segment starting from the target anchor point, iv) removing the target anchor point, and v) removing the media material matching the text segment starting from the target anchor point; and aligning the text segments with respective media matching materials.

Abstract: The present disclosure provides examples of a method and apparatus for processing a video, a device and a storage medium. The method may include: acquiring a target video and a target comment of the target video; recognizing a picture in the target video to obtain text information of the picture; determining a target comment matching a content of the text information; and inserting, in response to displaying the picture in the target video, the target comment matching the content in a form of a bullet screen.

Abstract: The present disclosure provides a system for MRI. The system may obtain a plurality of echo signals relating to a subject that are excited by an MRI pulse sequence applied to the subject. The system may perform a quantitative measurement on the subject based on the plurality of echo signals. The MRI pulse sequence may include a CEST module configured to selectively excite exchangeable protons or exchangeable molecules in the subject, an RF excitation pulse applied after the CEST module configured to excite a plurality of gradient echoes, and one or more refocusing pulses applied after the RF excitation pulse. Each of the refocusing pulses may be configured to excite one or more spin echoes. The one or more spin echoes excited by at least one of the one or more refocusing pulses may include a symmetric spin echo and one or more asymmetric spin echoes.

Abstract: Embodiments of the present disclosure disclose a method and apparatus for storing a media file and for searching a media file. A specific embodiment of the method includes: acquiring a semantic vector for characterizing semantics of a context of the media file, the context being a context of the media file in a webpage presenting the media file; and storing the semantic vector and the media file in association. Based on the corresponding relationship established by this embodiment, the semantic vector corresponding to the media file may be used to match the media file to ensure the semantic matching of the media file.
