A new study benchmarks five convolutional neural network (CNN) architectures for satellite land-cover segmentation, focusing on the efficiency-accuracy trade-off. The research found that MobileNetV2_v1, a lightweight model at 24.98 MB, achieved the highest accuracy (0.7906) and mean Intersection over Union (0.4625) on the DeepGlobe dataset. This lightweight model outperformed larger architectures like InceptionV3_v2 and VGG16_v2, demonstrating the effectiveness of optimized, transfer-learned models in resource-constrained remote-sensing applications. While strong in classifying urban, agricultural, and water categories, the models struggled with spectrally similar classes like rangeland-barren, indicating that architectural optimization alone cannot solve all segmentation challenges.
