Member Data Documentation

double MotionPyramid::sMaxTDelta [static, protected]

default maximum motion history gradient threshold

gradient orientation is considered valid if the difference between the maximum and minimum mhi values within a pixel neighborhood is lower than this threshold.

double MotionPyramid::sMinTDelta [static, protected]

default minimum motion history gradient threshold

gradient orientation is considered valid if the difference between the maximum and minimum mhi values within a pixel neighborhood is greater than this threshold.

int MotionPyramid::sApertureSize [static, protected]

default gradient aperture

size of aperture used to calculate derivatives. Value should be odd, e.g., 3, 5, etc.

IplImage** iso::tracker::MotionPyramid::mSilhouettes [protected]

motion masks

IplImage** iso::tracker::MotionPyramid::mMotionHistoryImages [protected]

motion history images

IplImage** iso::tracker::MotionPyramid::mMaskImages [protected]

motion mask images

mask image - marks pixels where motion gradient data is correct

IplImage** iso::tracker::MotionPyramid::mOrientationImages [protected]

motion orientation images

motion gradient orientation image; contains angles from 0 to ~360 degrees

double iso::tracker::MotionPyramid::mMaxTDelta [protected]

maximum motion history gradient threshold

gradient orientation is considered valid if the difference between the maximum and minimum mhi values within a pixel neighborhood is lower than this threshold.

double iso::tracker::MotionPyramid::mMinTDelta [protected]

minimum motion history gradient threshold

gradient orientation is considered valid if the difference between the maximum and minimum mhi values within a pixel neighborhood is greater than this threshold.

int iso::tracker::MotionPyramid::mApertureSize [protected]

gradient aperture

size of aperture used to calculate derivatives. Value should be odd, e.g., 3, 5, etc.

double iso::tracker::MotionPyramid::mTimeStamp [protected]

time stamp

timestamp for motion history
