The invention relates to the technical field of image recognition, and discloses a tattoo classification and recognition method, device and equipment and a medium, and the method comprises the steps: obtaining various types of
skin image data, carrying out the type labeling of the
skin image data, obtaining a
skin type image, determining the
skin appearance features of a to-be-recognized skin image according to the
skin type image, and carrying out the recognition of the
skin appearance features of the to-be-recognized skin image. And selecting a
feature extraction algorithm of the to-be-recognized skin image, performing point-by-point
convolution and deep
convolution on the to-be-recognized skin image to obtain a tattoo probability of each to-be-recognized skin image, and if the tattoo probability is smaller than or equal to a preset probability threshold, obtaining a judgment result that the
skin type of the to-be-recognized skin image is not a tattoo type, and if the tattoo probability is not greater than a preset probability threshold, judging that the
skin type of the to-be-recognized skin image is not the tattoo type. And if the tattoo probability is greater than a probability threshold, converting the to-be-recognized skin image greater than the probability threshold into a to-be-recognized skin sequence, obtaining a tattoo classification
label, and performing
feature recognition on the to-be-recognized skin sequence by using the tattoo classification
label to obtain a tattoo
classification result. According to the invention, the tattoo classification and identification accuracy is improved.
