In last few posts we had looked into various Affine transformation and we learned about the transformation matrix. Let’s summarize the Affine transformation matrices in this post with animation, which is written in pure Scilab script. (more…)
The last post of Affine Transform tutorial series would cover image shearing. Image shearing is commonly used to adjust the misaligned image to a better position for further processing for a better result.
Affine Transform usually used for translation, rotation and scaling of an image to correct its’ alignment which is distorted or deformed due to the imperfection of camera or limitation of the camera to be snap at desired angles.
In image processing, most of the time the used of convolution and correlation for filtering is more to personal preferences, as they perform almost the same operation. They are identical if the kernel is symmetrical.
