“…Since the last decade, deep CNNs, such as AlexNet [37], Inception [39], VGG [40], ResNet [41], and ResNeXt [42], ShuffleNet [43], MobileNet [44], RegNet [45], Transformers [46] and EfficientNet [47] have been successfully used for computer vision tasks. Their application for face recognition has been highly successful in accurately determining an individual's age, gender, and weight based on facial features extracted by deep CNNs from their faces [48][49][50][51][52][53][54][55][56]. In this study, we used tongue images rather than facial images to predict an individual's age, gender, and weight.…”
