分辨率

Owing to the existence of noise or quantization error, conventional gradient operators generally produce many local minima.

因此，本文提出了一种基于直接投影和分水岭结合的多分辨率分水岭算法来分割图像。

Based on the technique of radiate temperature measurement, the author designs a circuit of prismatic decomposition colorimetric radiate temperature measuring. A high resolution A/D converter and measurement range switch technology are adopted to resolve the problem that it has lower radiation power and lower signal sensitivity in the low-temperature stage, while higher signal amplitude and higher need of dynamic range in the high-temperature stage. The technique of the Black Body Furnace demarcates, digital calibration and the quartic curve fitting are applied to correct the sensor and improve its measurement precision.
