We report the effects of oxygen content on the transport properties of La 0.7 Ca 0.3 MnO 3-δ thin films grown epitaxially on LaAlO 3 (001) substrates by RF magnetron sputtering. The as-deposited thin films were annealed and treated by oxygen plasma to improve the oxygen content. We observe that the La 0.7 Ca 0.3 MnO 3-δ films annealed at 850°C is highly oriented growth on (001) LAO substrate. However, the XRD patterns of the samples annealed at lower than 850°C show no distinct diffraction peaks. This evidence indicates that the samples annealed at lower than 850°C are still amorphous or nanoc

The color constancy problem is one of calculating reflectance values for surfaces under differing illuminants. Retinex theory (e.g., Land, 1986) states that relative receptor responses are used to recover surface reflectance after they have been normalized with respect to the responses of neighboring receptor responses. Specifically, a number of paths to the pixel in question are randomly chosen and the logarithm of the ratio of the pixel receptor's response to the geometric mean of the receptor responses over a large number of paths is used as the lightness value for the pixel in question.
