HOG flags

Defines what features will be returned.

#define VPI_HOG_CONTRAST_SENSITIVE   0x01
 Return contrast sensitive features.
 
#define VPI_HOG_CONTRAST_INSENSITIVE   0x02
 Return contrast insensitive features.
 
#define VPI_HOG_TEXTURE   0x04
 Return texture-related features.
 
#define VPI_HOG_ALL_FEATURES   (VPI_HOG_CONTRAST_SENSITIVE | VPI_HOG_CONTRAST_INSENSITIVE | VPI_HOG_TEXTURE)
 Helper flag to return all features.
