Dull Razor algorithm : Problem with inpainting values

Hi guys, I am trying to implement the Rull Razor algorithm in matlab but when I try to inpaint the rgb image values with the binary mask, I can't find a function to do that .

PS: I tried inpaintCoherent and inpaintExemplar but I got the error that they are not defined

PS: I tried regionfill but its only applicated on the rgb image so the problem is that Ican't get the rgb image back

I will be grateful for anyone that help me with, thank you in advance

here is my code :

i=imread('ISIC_0031023.JPG');
%crop
[x,y,z] = size(i);
d = y-x;
i = i(:,round(d/2)+1:y-(d-round(d/2)),:);
figure,imshow(i);
%convert the rgb image to grayscale image
img=rgb2gray(i);
figure,imshow(img);
%black hat filter
SE=strel('disk',3);
J = imbothat(img,SE);

figure, imshow(J);
%apply gaussian filter 
Iblur1 = imgaussfilt(J);
figure,imshow(Iblur1);
%Binary thresholding (MASK)
BW = imbinarize(Iblur1);
figure, imshow(BW);
%replace the pixels of the mask
%f =inpaintExemplar(i,BW,'FillOrder','tensor','PatchSize',7);
%f=inpaintCoherent(i,BW);
%f=regionfill(img,BW);
figure,imshow(f);

Never heard of Rull Razor. Is that some kind of variant on the original Dull Razor?

You can use regionfill() on each color channel one at a time.

[r,g,b] = imsplit(i);
r = regionfill(r, BW);
g = regionfill(g, BW);
b = regionfill(b, BW);

Why do you do this:

[x,y,z] = size(i);

instead of

[rows, columns, numberOfColorChannels] = size(rgbImage);

??? First of all i should not be used since it's the imaginary variable. Secondly rows is called, by nearly everyone except you, as the y value, not "x" as you called it. And the columns is x, not y.

First, thanks a looooot for your solution, because it works, and second, the "rull razor" is just a typing error (I corrected it), and finaly I didn't understand your idea of ​​x and y, x is the number of rows and y is the number of columns but you said the opposite

[Image Analyst]

Yeah it's just that most people in the world call the vertical (rows) direction y, and you are not following that naming convention. And the rest of the world calls the horizontal direction x, and again, you're not following the worldwide convention. Yes, the code still works because you are consistent in the way you name and use the indexes.

okay I got your idea, thank you so much for explaining
