So I have two images:
How can I calculate the number of elements (pixels in each image) that represents the sea area assuming sea area in 1957 is 68km^2?
Some of the initial guidlines:
(a) initialize the black and white images with zeros.
(b) use logical operation to replace all matrix elements that is <=180 to 1, the rest of the elements remains as 0.
(c) use matrix addressing to exclude the text at the bottom of the image in your calculation
(d) sum up the ones in the black and white image as the sea area.
finally, Write the year, estimated sea area by pixel and estimated sea area by km2 into a text file named AralSeaAreaData.txt.
Thank you so much
