Abstract: Image data in a first color space is converted to image data corresponding to a second color space. Image processing of the image data occurs in the second color space. After image processing is complete, the image data is then converted to image data in any one of the following color spaces: 1) the first color space, 2) a third color space, or 3) the second color space but using a conversion method that is different than the conversion method used to convert the image data from the first color space to the second color space.

Abstract: A method includes receiving color image data arranged in a non-square color image pattern, such as RGB raw data in a Bayer pattern. G-plane color image data of the non-square color image pattern is mapped to a substantially square color image pattern. Compression and decompression of the G-plane color image data of the substantially square color image pattern is performed. After decompression, the decompressed G-plane color image data is remapped into another G-plane color image pattern that is substantially the same as the original non-square G-plane color image pattern. Interpolation from an RGB space to another color space, such as a YCbCr space, can be subsequently performed, along with or in addition to image enhancement processing.

Abstract: Positron annihilation radiation lineshapes from two-dimensional angular correlation and Doppler broadened spectrum measurements are used to monitor specific surface acidity (proton concentration per unit surface area) of catalytic materials with large internal surface areas. Annihilation gamma lineshape parameter increases with internal surface area and decreases with specific surface acidity as a result of oxidation of positronium atoms at the surface by protons. These results point to a new and effective method for specific surface acidity valuations.
