CLASSIFICATION OF STRAWBERRY FRUIT SHAPE BY MACHINE LEARNING
Shape Recognition Classification Measurement Chain code Machine learning Random Forest Agriculture
2018/6/4
Shape is one of the most important traits of agricultural products due to its relationships with the quality, quantity, and value of the products. For strawberries, the nine types of fruit shape were ...
Shape optimization of lightweight structures under blast loading
design under uncertainty blast loading
2015/1/12
Structural optimization of vehicle components for blast mitigation seeks to counteract the damaging effects of an impulsive threat on occupants and critical components. The strong and urgent need for ...
Fourier Descriptors with Different Shape Signatures: a Comparative Study for Shape Based Retrieval of Kinematic Constraints
Fourier Descriptors Kinematic Constraints Shape Based Retrieval
2011/8/5
Fourier Descriptors (FD) has been widely used in image analysis and computer vision for shape recognition as they can be made independent of translation, rotation, as well as scaling. They have also b...
