De-Convolution without DFT using OpenCV

edit

HI I want to develop a code using OpenCV Mat for deconvolution of an image in spatial domain without making dft, given the kernel and input image., Is there any procedure to do this or it is not possible , basically I want to make deblurring to blurred image with a given kernel , angle and length of motion blur . I want to make deblurring the image using the given kernel , but without any DFT .

Please make a feasible answer to me.

Thanks pixolish
