| - | The Image Stitching function is similar to a function of panarama stitching in photoprocessing. If you have a set of images, made with an otherlap of at least 10 %, the function **Image stitching** enables to combine them into one big image of the surface. | + | The Image Stitching function is similar to a function of panorama stitching in photo processing.

| - | It's time to figure out how the function works. The main idea of this algorithm is to find a correlation between areas located on the edges of the frames. On the first step of the algorithm the program looks for local maximums of correlation. According to the strongest maximums the images are stitching. In the course of the algorithm it uses the following parameters ([[:en:processing:stitching_parameters_scheme|see the scheme]]): | + | It's time to figure out how the function works.

| * **Margin** -- occasionally edges of AFM images are distorted with hysteresis or with temperature drift, in this case consideration of these data in correlation calculation is undesirable. This parameter allows to indent on the edge of the image. The parameter value is specified as a fraction of the length of the image, the default value for this parameter is zero. | * **Margin** -- occasionally edges of AFM images are distorted with hysteresis or with temperature drift, in this case consideration of these data in correlation calculation is undesirable.
