What is the photon energy of light with a wavelength of 941 nm Note that h = 6.626 × 10−34 J·s and c = 3.00 × 108 m/s.
For this project, you are to implement a prototype of “Photo Booth” by using different kernels for image filter. The input image is obtained directly from the web camera captured video. Your task is to apply different kernels triggered by hitting different keys on the keyboard: (1) Hit “i” shows the original video The “identical” […]
