The first step in Image Processing is:

• Segmentation

• Image acquisition

• Image enhancement

• Image restoration

The shortest discernible change in the level of intensity is known as:

• Contrast

• Saturation

• Contour

• Intensity Resolution

Which of these operations is done, in the spatial domain, on the pixels when we want to sharpen the image?

• Median

• Differentiation

• Average

• Integration

An alternate approach used in place of the median filtering is:

• Sharpening

• Laplacian filter

• Gaussian filter

• Using a mask

The total pixels in any given region defines the:

• Brightness

• Intensity

• Perimeter

• Area
