Embodiment Construction
[0051] Below in conjunction with accompanying drawing and embodiment further illustrate method step of the present invention:
[0052] The first step: read in the image as the original reference image (attached figure 1 ), then along the direction to move 30 pixels horizontally to the left, The direction moves 20 pixels vertically downward, rotates (-15) degrees (set clockwise rotation as the positive direction), and enlarges the whole by 1.25 times. The image after space transformation is used as a floating image;
[0053] Step 2: Use the Fourier-Mellin transform algorithm for fast coarse registration to obtain the rough registration parameters, then use the Brent one-dimensional search algorithm and the improved Powell multi-dimensional direction optimization algorithm for precise registration to obtain the precise registration parameters using MSSIM as the measure. registration parameters;
[0054] Step 3: Space transform the original floating image with coarse regist...
