Web16 apr. 2024 · Added to the complex nature of the interpretation of image formation is the unfortunate way in which it is usually represented when optics is being taught, which leads pupils to think, for example, that specular reflection and diffuse reflection are one and the same phenomenon. WebMethods of low-level image processing operate on the raw data as well as a pixel, edge, or texture levels, and thus at a minimal level of abstraction. Methods of high-level image processing include the texture, region, object, and scene levels. The required abstraction can be achieved by an increased modeling of a-priori knowledge.
