EDGE DETECTION OF BLASTING PILES BASED ON TWO DIMENSIONAL WAVELET TRANSFORM |
| |
| Abstract: | According to gray distribution features of images of blasting piles and the principle of wavelet transform on edge detection,B-spline wavelet having ability of detection of partial abrupt change was adopted to carry out edge detection of rock fragmentation size of blasting piles.The filter of B-spline wavelet was given by derivation,and edge detection algorithm based on two-dimensional wavelet transform was designed according to filter of B-spline wavelet.The detection arithmetic of self-adaptive threshold was designed in the wavelet edge division,and the arithmetic could remove noise of image and well reserve its edge. |
