    I read some comments where were people complaining about getting 3 images, this is due to they are resizing RGB image while the code is for gray-scale images

    @Sourav Mishra: The c matrix is a double one when we assign construct it using zeros(). U can check the type of the variable by whos or in the variable details

    why is c/255 required when we have assigned elements of a directly to elements of c.
    so both a and c are expected to be of uint8 type.

    hello rashi , Great information from your videos :)
    In the 14th line we take c/255 for imshow()
    why dont we take c/255 for imagesc()

    Your all videos are really helpful, but I have a suggestion for you sister that you should ZOOM IN the code area, so it would be more clear for us. Thanks

    14th line is simply: figure,imshow(c/255)

      hi rashi, first of all thank you for the video it helps a lot. i used your code to resize my pic but i dont understand why do i get the photo 3 times in one figure
      here is my code :
      l=imread('dani_smartphone2.jpg');
      [rows,columns]=size(l);
      i=1; j=1;
      c=zeros(rows/2,columns/2);
      for x=1:2:rows
      for y=1:2:columns
      c(i,j)=l(x,y);
      j=j+1;
      end
      i=i+1;
      j=1;
      end
      figure,imshow(c/255);
      colormap(gray);

    Hi,
    when the image pixel size is doubled or increased., so we will need to add something in between so what does it add at the position in between,.

    • @hundaeece5763

      I think Matlab uses zero order hold resizing, so if you resized the image up to scale 4 in both directions, each pixel will be replicated 16 times in a completed square ( new large pixel ).

    Just asking, can imresize be used in zooming (zero order hold method)? Btw your videos are really helpful. New subscriber here :))

    c = a (1:2:N, 1:2:M, : );
    I believe this line would make the same as all the for loops

    As you haven't applied jet colormap on the image its simply an grayscale image then why you are using grayscale colormap....??
