4.2 A 512x512 gray scale image contains a sinusoidal pattern as shown below. 4.2.1 Formulate this image, i.e. provide analytical expression as a 2-D discrete time function. (Hint: similar to page 14 in CpE462-5.ppt). 1.e image is directly placed in front of the eye at 250 mm away, and the eye is 20 mm in diameter with a focal point of 3 mm from the lens, calculate the period of its projection on retina in distance (mm) and in degree (). 2.5mm 10 250mm 3mm10mm 4.2 A 512x512 gray scale image contains a sinusoidal pattern as shown below. 4.2.1 Formulate this image, i.e. provide analytical expression as a 2-D discrete time function.
