Abstract: An image semantic segmentation algorithm and system based on multi-channel deep weighted aggregation where the image semantic segmentation algorithm is based on multi-channel deep weighted aggregation. The aggregation includes semantic features with definite class information in an image, transition semantic features between low-level semantic and high-level semantic, and semantic features of context logic relationship in an image are extracted by a low-level semantic channel, an auxiliary semantic channel and a high-level semantic channel, respectively. The aggregation further includes three different semantic features obtained in S1 are fused by weighted aggregation to obtain global semantic information of the image; S3, the semantic features output from respective semantic channels in S1 and the global semantic information in S2 are used to compute loss function for training.

Abstract: In a data processing method that based on an instant messaging application and which is performed by a data processing device, audio data from an instant messaging application is obtained, and sampled volume data corresponding to the audio data is obtained based on a sampling frequency. A spectrogram corresponding to the audio data is generated according to the audio data and the sampled volume data, and a message bar comprising the spectrogram and the audio data is outputted. Audio progress control is then performed on the audio data in response to a target trigger operation on the message bar, and display control is performed on the spectrogram based on an audio progress.

Abstract: The invention discloses an anti-phenacetin monoclonal antibody hybridoma cell strain AD, a preparation method and application thereof, and relates to the technical field of food safety immunodetection. The monoclonal antibody hybridoma cell strain is named monoclonal cell strain AD and the number CGMCC19681. The Phe-BA obtained by the hydrolysis of the reaction product of the phenacetin metabolite acetaminophen and ethyl 4-bromobutyrate is used as the hapten, and the hapten is coupled with the carrier protein to prepare the immunogen Phe-BA-BSA. After the mice were immunized with the immunogen Phe-BA-BSA, they were fused with myeloma cells by PEG method, screened by indirect competitive enzyme-linked immunosorbent assay and subcloned five times to obtain hybridoma cell lines. The monoclonal antibody secreted by the cell line can be made into a phenacetin detection kit, which has good affinity and detection sensitivity for phenacetin, and can be used for immunodetection of phenacetin residues in food.
