WebAug 15, 2024 · Although masks are binary, they can be applied to images to filter out pixels where the mask is False. NumPy's where () function is a flexible way of applying masks. It takes three arguments: np.where(condition, x, y) condition, x and y can be either arrays or single values. This allows you to pass through original image values while setting ... A conventional photomask is a transparent plate with the same thickness everywhere, parts of which are covered with non-transmitting material in order to create a pattern on the semiconductor wafer when illuminated. In alternating phase-shift masks, certain transmitting regions are made thinner or thicker. That induces a phase-shift in the light traveling through those regio…
