(a) Pixel replication ( M = 4) (b) mm int g interpolated Fig. 12. The interpolation with mm int g of a real life scene (a cut-out of the Lena image) 6 Conclusions We presented a greyscale solution for the binary morphological interpolation technique mm int . A temporary local binarization of the grey values, combined with a local majority ordering, makes it possible to perform the morphological hit-miss transform on the image. The grey values of the pixels that need to change value, are defined in terms of neighbouring pixel values. The visual quality of the new mm int g is very good for cartoon sprites and line graphics. Its results are in most cases visually better than those of hq . References 1. Lehmann, T., G¨ onner, C., Spitzer, K.: Survey: Interpolations Methods In Medical Image Processing.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
