cv.cornerMinEigenVal - MATLAB File Help
cv.cornerMinEigenVal

Calculates the minimal eigenvalue of gradient matrices for corner detection

dst = cv.cornerMinEigenVal(src)
dst = cv.cornerMinEigenVal(src, 'OptionName', optionValue, ...)

Input

Output

Options

The function is similar to cv.cornerEigenValsAndVecs but it calculates and stores only the minimal eigenvalue of the covariance matrix of derivatives, that is, min(lambda_1,lambda_2) in terms of the formulae in the cv.cornerEigenValsAndVecs description.
