CMeasure

class ikomia.core.pycore.CMeasure

Class to handle available measures that can be computed on blob object in image (ie connected component). Here is the list of possible measures (MeasureId):

  • Surface: cv::contourArea

  • Perimeter: cv::arcLength

  • Centroid: computed from moments or average on points coordinates if moments are not available cv::Moments

  • Bbox: cv::boundingRect

  • Oriented bbox: cv::minAreaRect

  • Equivalent diameter: estimation based on blob surface

  • Elongation: computed from R. Mukundan and K.R. Ramakrishnan. Moment Functions in Image Analysis –Theory and Applications. World Scientific, 1998

  • Circularity: computed from surface and perimeter -> circularity = (4*PI*surface) / (perimeter²)

  • Solidity: computed from the convex hull -> solidity = surface / hullSurface
