We show the possibilities of type-II intracavity Second Harmonic Generation as a way to perform all-optical parallel processing of images. To do image processing operations we pump the crystal at two orthogonal polarizations at fundamental frequency, the y-polarized pump is an homogeneous wave and the x-polarized pump has an spatial dependence that represents the image to be processed. Depending on the relative intensities between the two pumps, different operations can be done. If the intensity of the homogeneous pump is greater than the intensity of the x-polarized pump we obtain at the output of the system the same image but at second harmonic frequency and in the y-polarization. Also the inverted image appears in the y-polarization at fundamental frequency. If the intensity of the homogeneous field is lower than the x-polarized field in some regions of the image this regions appear enhanced in the x-polarized fundamental field at the output of the system, and in the second harmonic we obtain the contour of the image. Furthermore the system shows noise filtering properties. We show that injecting two images simultaneously it is possible to perform logical operations such as \
