Special Issue Information

Dear Colleagues,

With the rapid development of artificial intelligence, deep learning technology, as an important subset of AI, enables models to autonomously infer results from structured datasets without the need for explicit human intervention. Deep learning has far surpassed traditional techniques and even human capabilities. Deep learning has achieved significant results in various image processing tasks, including image classification, object detection, image segmentation, and image enhancement.

This Special Issue on “Deep Learning and Digital Image Processing” seeks high-quality research focusing on the basic principles, core algorithms, network structure designs, and specific applications in image processing of deep learning. Topics include, but are not limited to, the following:

  1. Deep learning for image super-resolution.
  2. Object detection, tracking, and recognition.
  3. Deep learning for image segmentation.
  4. Neural networks and deep learning.
  5. Low-level visual understanding and image processing.
  6. Feature extraction and feature selection.
  7. Document analysis and recognition.
  8. Activity recognition.
  9. Multimedia analysis and inference.
  10. Remote sensing image interpretation.
  11. Medical image processing and analysis.
  12. Visual issues in multimodal information processing.
  13. Time series analysis.

Ginseng is a common medicinal herb with high value due to its unique medicinal properties. Traditional methods for classifying ginseng rely heavily on manual judgment, which is time-consuming and subjective. In contrast, deep learning methods can objectively learn the features of ginseng, saving both labor and time. This experiment proposes a ginseng-grade classification model based on an improved ResNeXt50 model. First, each convolutional layer in the Bottleneck structure is replaced with the corresponding Ghost module, reducing the model’s computational complexity and parameter count without compromising performance. Second, the SE attention mechanism is added to the model, allowing it to capture feature information more accurately and precisely. Next, the ELU activation function replaces the original ReLU activation function. Then, the dataset is augmented and divided into four categories for model training. A model suitable for ginseng grade classification was obtained through experimentation. Compared with classic convolutional neural network models ResNet50, AlexNet, iResNet, and EfficientNet_v2_s, the accuracy improved by 10.22%, 5.92%, 4.63%, and 3.4%, respectively. The proposed model achieved the best results, with a validation accuracy of up to 93.14% and a loss value as low as 0.105. Experiments have shown that this method is effective in recognition and can be used for ginseng grade classification research. Full article
