The invention discloses an ecological biological recognition method based on an SPP-Net algorithm, and the method comprises the following steps: initiating an ecological biological recognition request, and collecting biological image data in an ecological environment according to the request; preprocessing the acquired biological image data by adopting an image normalization method and an image enhancement method to obtain preprocessed biological image data; performing target detection on the preprocessed biological image data through an SPP-Net algorithm; and matching the detected biological image with the image information, and carrying out ecological biological recognition. According to the method, the whole image is input and the feature map of the whole image is extracted through the setting of the SPP-Net algorithm, and then the features of each region proposal are extracted from the feature map of the whole image in the spatial pattern pooling layer by using the spatial relationship, so that the size of the image does not need to be considered, the fixed-length network structure of the image is output, the expression is stable under the condition of image deformation, and the accuracy of the image deformation is improved. And the operation speed is high.
Description
technical field [0001] The invention relates to the technical field of biological identification, in particular to an ecological biological identification method based on the SPP-Net algorithm. Background technique [0002] With the continuous development of computer technology, biometric technology has been widely used. Among them, biometric technology refers to the use of inherent physiological characteristics and Behavioral features for biometric authentication. [0003] Aquatic biome and water environment have intricate interrelationships, and play an important role in water quality changes. Different types of aquatic organisms have different adaptability to water pollution, and some species are only suitable for living in clean water, which are called clear water organisms (or oligopollution organisms). Some aquatic organisms can live in sewage and are called sewage organisms. The survival of aquatic organisms marks the degree of water quality change, so organisms be...
