Example text

Here, the numbers [0], [1], [2] are used to access the blue, green, and red components respectively. uchar averageValue = static_cast(tSum/3); We now calculate the average value of the pixels. at(j,i)[2]= 255; // Red component of the pixel } Here, we will check whether the average value of each pixel is greater than the threshold value or not. If a particular pixel value satisfies the preset logic, its value is greater than the threshold value, so we will change the value of all the components of that pixel to white (255).

Here, the numbers [0], [1], [2] are used to access the blue, green, and red components respectively. uchar averageValue = static_cast(tSum/3); We now calculate the average value of the pixels. at(j,i)[2]= 255; // Red component of the pixel } Here, we will check whether the average value of each pixel is greater than the threshold value or not. If a particular pixel value satisfies the preset logic, its value is greater than the threshold value, so we will change the value of all the components of that pixel to white (255).

It is the combination of the values of these three individual components which decides the resulting color in the image at that pixel. Each of these three components has values ranging from 0 to 255, where 0 would represent black and 255 would represent white. So, we have to take into consideration the values of all three components. Our program in this case would first obtain the value of the three components, compute the average value (let us call it the average pixel value), and then use this value to compare with the predetermined threshold value.
