Study of mixed kernel effect on classification accuracy using density estimation
Sub-Pixel Support Vector Machine (SVM) Mixed Kernel Function
2015/8/20
Support Vector Machines (SVMs) are a statistical learning theory based techniques and have been applied to different fields. For the
pattern recognition case, SVMs have been used for isolated handwri...
Density estimation is a commonly used test case for non-parametric estimation
methods. We explore the asymptotic properties of estimators based on thresholding of
empirical wavelet coecients. Minim...
OBJECT BASED FOREST STAND DENSITY ESTIMATION FROM VERY HIGH RESOLUTION OPTICAL IMAGERY USING WAVELET BASED TEXTURE MEASURES
