Abstract : Diabetic Foot Ulcer (DFU) is a severe complication of diabetes, and it may cause lower limb amputation. However, the manual diagnosis of DFU is a complicated and expensive process. The primary objective of this work is to design an efficient Convolutional Neural Network (CNN) approach to identify DFU. Therefore, a novel CNN-based approach (AESPNet) is proposed in this paper, where convolution layers are stacked together in a parallel fashion and with an intermediate attention module to perform DFU vs -normal skin classification. The AESPNet consists of 2 blocks, where varying-sized kernel convolution layers are connected in a parallel fashion for better local and global feature abstraction. A bottleneck attention module is associated after every concatenation operation in the network. The Stochastic Gradient Descent (SGD) (with momentum) optimizer with

 learning rate is used to train the proposed network on a privately accessed DFU dataset. The results of the proposed approach are compared with other standard CNN-based schemes, namely AlexNet, VGG16, DenseNet121, and InceptionV3. It has been found that the proposed AESPNet outperforms state-of-the-art schemes with a sensitivity score of 98.44% and 0.98 F1-Scores.
