[0032] Example one
[0033] Such as figure 1 As shown, the protein data feature extraction method of this embodiment includes the following steps:
[0034] S1. Preprocess the original 3D model of protein, including data type conversion and data size standardization, to obtain a preprocessed 3D model;
[0035] The original three-dimensional model of protein is not uniform in size during construction and the selected scale is inconsistent. The pdb format file is used to describe the three-dimensional position of each atom and the off format file is used to describe the protein molecular surface. These files are not conducive to feature extraction. Therefore, in this step, the original file is converted into a data type file that is convenient for processing, and the data size is standardized to facilitate unified processing.
[0036] S2. Acquire multiple two-dimensional views of the preprocessed three-dimensional model, extract the image feature matrix of each of the two-dimensional vi...
