Can a binary image be converted into color image by using the following equation?

were,fxy x and y values of a binary image fand i varies from i=0 to 7.Then does pxy forms a RGB image?
Or what would be the value of pxy?

No, that expression is for updating a location, not for converting it to color.
There is not enough information to interpret the formula much further.

No, you need either divisions or a bunch of shifts and subtractions to convert binary to decimal.
It might be trying to talk about converting binary fractions or floating point values to integer, but if so then it needs either a round() or a floor() around the fx,y * 2^i part.

No. To convert a binary image to a color image that is 3-D but black and white, concatenate your binary image to three planes in the Z direction:
rgbImage = cat(3, binaryImage, binaryImage, binaryImage);
