Detection of and correction for specular reflections in digital image acquisition

摘要: Image processing parameters for gradation correction of a digital image from scene, which includes specular reflections may be seriously influenced by the presence those reflections. Therefore, method is developed to detect in modify exposure time photo-sensitive means, converts luminous electronic signals and apply data thus acquired. In one embodiment camera used capture data, cumulative histogram built two characteristic frequencies are determine via densities highlight densities. The relative position these density values indicates whether present, give suitable setting an optimal computing curve.
