Digital image processing tutorial

it is pretty straight forward. You actually hide the region which you dont want for variuos reasons. OR you can mask and extract the region which you want. You can do both.

Ok, i got it.

But in this attached image, even after applying the mask, the whole image under inspection is getting converted by the invert function.

Just have a look.

I think i am missing something in my understanding

Here is a course being offered in the near future:

Hi,

I think you are referring to image 1-4d. This image is just the inverse of the inspection image without the mask.

If you look at 1-4c, only the part of the image inside the mask is inverted.

Hi Voodoo

I got it, on inspection image, inversion function is applied with and without mask just to reveal the difference

Query 2:

What is the difference between Gray, temperature, rainbow and gradient palette?

In what different situations these are used?

[muks]

Display the color palette for the current image. You can change the palette to one of five predefined image palettes to show details not perceived with the current palette. Changing the palette here does not change the content of the image.

Gray Levels—Gradual grayscale variation from black to white. Each value is assigned an equal amount of the RGB intensities. Binary—16 cycles of 16 different colors, where g is the grayscale value and g = 0 corresponds to R = 0, G = 0, B = 0 (black); g = 1 corresponds to R = 1, G = 0, B = 0 (red); g = 2 corresponds to R = 0, G = 1, B = 0 (green); and so on. Gradient—Gradation from red to white with a prominent range of light blue in the upper range. 0 is black and 255 is white. Rainbow—Gradation from blue to red with a prominent range of greens in the middle value range. 0 is black and 255 is white. Temperature—Gradation from light brown to dark brown. 0 is black and 255 is white.

OK thanks MUKS

I am reading from the manual itself but wasnt able to understand. Thats why, i had to come here.
