Fig. 3From: Deep indicator for fine-grained classification of banana’s ripening stagesThe proposed CNN architecture. The original, positive, negative images, and label of the original image are taken as input in the framework. The yellow circle, red circle, and blue circle represent the l2 normalized vector of original image, positive image, and negative image, respectively. The structured feature represents the extracted features from the CNN framework. Two types of losses are exploited to obtain the fine-grained classification resultsBack to article page
