Calculate PHOG features

Description

Calculate PHOG features

Usage

PHOG_features(
  im,
  level = 3,
  n.bin = 8,
  is.orientation = TRUE,
  starts.horizontal = TRUE,
  clockwise = FALSE,
  level.weight = c(1, 1, 1)
)

Arguments

`im`	an image
`level`	number of PHOG pyramid levels
`n.bin`	number of orientation/direction bins
`is.orientation`	TRUE for orientation (0-180 degrees), FALSE for direction (0-360 degrees)
`starts.horizontal`	if TRUE, the first bin is centered at 0 degree
`clockwise`	direction of rotation
`level.weight`	relative weights to each level for calculating self-similarity
