Timely and accurate acquisition of crop distribution and planting area information is important for making agricultural planning and management *** study employed aerial imagery as a data source and machine learning as a classification tool to statically and dynamically identify crops over an agricultural cropping *** analysis of pixel-based and object-based classifications was performed and classification results were further refined based on three types of object features(layer spectral,geometry,and texture).Static recognition using layer spectral features had the highest accuracy of 75.4%in object-based classification,and dynamic recognition had the highest accuracy of 88.0%in object-based classification based on layer spectral and geometry *** identification could not only attenuate the effects of variations on planting dates and plant growth conditions on the results,but also amplify the differences between different ***-based classification produced better results than pixel-based classification,and the three feature sets(layer spectral alone,layer spectral and geometry,and all three)resulted in only small differences in accuracy in object-based *** recognition combined with objectbased classification using layer spectral and geometry features could effectively improve crop classification accuracy with high resolution aerial *** methodologies and results from this study should provide practical guidance for crop identification and other agricultural mapping applications.

Introduction Cell mechanosensing is the process that cell senses extracellular mechanical cues through mechanosensors and transduces them to downstream signaling pathways to alter cell mechanics and behaviors,which is involved in embryonic development(Gaetani et al.,2020),tissue regeneration(Fu et al.,2019),inflammatory response(Worbs et al.,2017),and tumor invasion and metastasis(Gargalionis et al.,2018).This ability is crucial for cells to adapt to mechanical stimuli(compressive force,shear stress,substrate rigidity,topology,adhesiveness,etc.)and maintain homeostasis(Chen et al.,2017).
