The invention provides an image recognition method based on a computer, and the method comprises the following steps: carrying out the digitalization of a recognized image; carrying out the preprocessing of the digital information; carrying out the feature selection of the digital information after preprocessing, selecting a feature value of a to-be-recognized image, and extracting the information comprising the feature value from the digital information after preprocessing; enabling a to-be-recognized feature value to be mapped to a feature space from an object space in a feature value extraction process; keeping the digital information of the to-be-recognized feature value in the digital information after preprocessing, eliminating other digital information, and obtaining the to-be-recognized digital information; reverting the to-be-recognized digital information to an analog image. The method provided by the invention carries out the digitalization of the image, carries out the feature selection of the digitalized image and carries out the recognition of the image through the feature value, thereby greatly improving the recognition accuracy and speed.
Description
technical field [0001] The invention relates to the field of image technology, in particular to a computer-based image recognition method. Background technique [0002] Images are used as analog signals. In the prior art, most of the recognition is through human eyes, and recognition through computers has also begun to appear. However, it is currently difficult to carry out digital recognition through computers. Both are higher than the traditional way, and there is no means of digital processing at present. Contents of the invention [0003] In order to solve the above technical problems, the invention provides a computer-based image recognition method, which includes the following steps: [0004] Digitize the recognized image and change it into digital information suitable for computer processing; [0005] Preprocessing the digital information to remove interfering information and reduce distortion or distortion; [0006] performing feature selection on the preprocess...
