Which of the following measures are not used to describe a region?(a)

1.	Which of the following measures are not used to describe a region?(a) Mean and median of grey values(b) Minimum and maximum of grey values(c) Number of pixels alone(d) Number of pixels above and below meanI have been asked this question in my homework.This question is from Regional Descriptors in portion Representation and Description of Digital Image Processing
Answer» Right answer is (c) Number of pixels alone Easiest explanation: Some of the measures which are used to describe a REGION are MEAN and MEDIAN of GREY values, minimum and maximum of grey values and number of pixels above and below mean. The area of the region, i.e., the total number of pixels in the region cannot alone describe the region.
