Background:

Accurate appearance quality classification of Auricularia auricula (wood ear mushroom) is crucial for industry advancement.
Existing methods may lack the precision and speed required for real-time industrial applications.

Purpose of the Study:

To develop an intelligent appearance quality classification method for Auricularia auricula.
To enhance the accuracy and real-time performance of quality classification using an improved Faster RCNN framework.

Main Methods:

An improved Faster Region-based Convolutional Neural Network (Faster RCNN) framework was developed.
A multiscale feature fusion detection model was established to integrate shallow and deep features.
The model was evaluated by comparing its performance against the original Faster RCNN.

Main Results:

The improved Faster RCNN achieved a 2.13% increase in mean average precision (mAP).
Significant improvements in average precision (AP) were observed for second-level (nearly 5%) and third-level (1%) Auricularia auricula.
Processing speed increased from 6.81 to 13.5 frames per second (FPS).

Conclusions:

The multiscale feature fusion approach effectively enhances Auricularia auricula detection accuracy and speed.
The improved Faster RCNN offers a viable solution for intelligent, real-time quality classification in the industry.
Further analysis explored the impact of environmental complexity and image resolution on detection outcomes.
