The main body of a book the definition that the wave shifts from childhood and the signal characteristic property different from noise start off contacting home and abroad's having studied current situation is analytical various go and chirp method, threshold value among them minor wave including that model extremely large value going to chirp , minor wave modulus correlativity going to chirp, goes to chirp. The denoise having been in progress to the signal handles the method middle , the main body of a book applying a part are applied go and chirping all above several kinds , include the treatment to one thinking signal and the two-dimensional picture signal among them, we can see the signal mass going to after chirping from the signal middle have handled better than containing the signal chirping , the final contrast has been analysed obviously various go and chirp excellent method shortcoming. |
