The fiber mouthfeel of fish muscle is a highly sought-after goal for surimi gel *** primary aim of research and development has been to quickly and accurately evaluate fiber degree for fish ***,based on the ResNet model,edge feature attentional mechanism was introduced to obtain the edge feature attention net (EFANet) to evaluate fiber degree for fish *** EFANet was trained and tested on a dataset,which was made by collecting microscopic pictures of fish samples with different degrees of *** with the three classic convolutional neural network (CNN) models,the EFANet emphasizes the learning of fiber texture information for fish muscle,reduces the effect of image color change,and significantly improves the detection *** average accuracy and specificity of the EFANet-50 on the testing dataset were 96.22% and 97.92%,respectively,which proved that it can effectively predict the fiber degree of fish muscle.
