GCS-YOLO: A Lightweight Detection Algorithm for Grape Leaf Diseases Based on Improved YOLOv8
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe authors based upon the YOLOv8 model propose an improved computer vision structure for classification and object detection implemented on images of grape leaf diseases. The proposed structure incorporates to YOLOv8 modules such as Ghost Modules, Reparameterized Convolution (RepConv) modules, Convolutional Attention Modules (CBAM), and a Shared Convolutional and Separated Batch Normalization Detection Head (SSDetect) module in order to achieve better performance simultaneously reducing the number of parameters and computational cost for real-time application. On the Plant Village Dataset the proposed model achieves superior inference speed and detection accuracy in terms of metrics such as mAP, GFLOPs, and FPS. A comparative analysis and an ablation analysis justifies the improved performance.
The manuscript is well written and the work is well presented.
Please find below some minor comments:
- In line 120, please explain CBS, C2f, and SPPF abbreviations.
- In line 135, the C2f-GR module is firstly mentioned. A reference to the figure 7 which follows should be added to facilitate readability.
- Lines 188 to 191. During training the structure is different than during inference. Please explain how the parameters (i.e. weights) of the inference phase acquire values since they are not trained.
- Lines 341 to 344. There is an incorrect repetition.
- A discussion section is missing even though meaningful discussion is integrated in other sections.

The manuscript entitled “GCS-YOLO: A Lightweight Detection Algorithm for Grape Leaf Diseases Based on Improved YOLOv8”
This study investigates the GCS-YOLO, a lightweight grape leaf disease detection algorithm based on an improved YOLOv8. It incorporates the C2f-GR module, RepConv, and CBAM to enhance feature extraction and detection efficiency. The model achieves a 45% reduction in parameters and computational load, with a 1.3% increase in mAP, making it suitable for real-time and edge deployment. Despite the well-executed study, there are areas requiring further clarification to confirm its applicability. However, I have the following comments that will improve the quality of the manuscript.:
- How does poor image quality, like low resolution, noise, or obstructions, affect the algorithm's accuracy, especially in field conditions?
- Does GCS-YOLO lack transparency in its decision-making process, and how could this be a problem if users need detailed explanations for predictions in critical agricultural applications?
- The author should define the abbreviation FAO before using it as an abbreviation for the first time, please check for others in the manuscript.
- The quality of Figure 10 can be improved as it is difficult to understand.
