7. November 2, 19987 Color Edges Color Edges in 2 or more bands may always have non-zero first order variation in all image directions at an edge point. Edge strengths arise from the 2 eigenvalues of a 2x2 symmetric matrix. The corresponding eigenvectors are the respective edge directions. Color Canny Edges arise from the first order variation of the largest eigenvalue along the direction of the respective eigenvector
