关键词： Cardamom pods   Deep Learning   Grad-CAM   Kotlin   Multi-scale domain generative adversarial network   Multispectral imaging  

摘要： Classification of cardamom pods remains a challenging task due to changes in lighting, inconsistencies in texture, and spectral features that overlap with existing methods, which lack the attributes of robustness, interpretability, and real-time usability. This research addresses the aforementioned issues by introducing an advanced dual-stream deep learning model, Di-stream improved Divine Religions Planarian ConvNeXt (DDRPCNeXt), which combines deep spatial features with handcrafted descriptors for enhanced discrimination of spectral and textural features. Supported by the Improved Divine Religions Algorithm (IDRA) metaheuristic optimizer, the model gets to enjoy fast convergence and stable training. Gradient-weighted Class Activation Mapping (Grad-CAM) guarantees that predictions are transparent and interpretable by showing visual heatmaps. The system is made available via a Kotlin cross-platform mobile application, which allows for on-device real-time classification. When tested with a dataset consisting of 1000 high-resolution cardamom images, the framework demonstrated outstanding performance, recording 99.25% accuracy, 99.09% precision, and 99.15% recall and F1-score. Such results validate the suggested solution as a tool for automated agricultural quality control that is accurate, interpretable, and ready to be used in the field.
