Superpixels intuitively over-segment an image into small compact regions with homogeneity. Owing to its outstanding performance on region description, superpixels have been widely used in various computer vision tasks as the substitution for pixels. Therefore, efficient algorithms for generating superpixels are still important for advanced visual tasks. In this work, two strategies are presented on conventional simple non-iterative clustering (SNIC) framework, aiming to improve the computational efficiency as well as segmentation performance. Firstly, inter-pixel correlation is introduced to eliminate the redundant inspection of neighboring elements. In addition, it strengthens the color identity in complicated texture regions, thus providing a desirable trade-off between runtime and accuracy. As a result, superpixel centroids are evolved more efficiently and accurately. For further accelerating the framework, a recursive batch processing strategy is proposed to eliminate unnecessary sorting operations. Therefore, a large number of neighboring elements can be assigned directly. Finally, the two strategies result in a novel synergetic non-iterative clustering with efficiency (NICE) method based on SNIC. Experimental results verify that it works 40% faster than conventional framework, while generating comparable superpixels for several quantitative metrics—sometimes even better.

The size and shape of diffraction spots produced by monochromated synchrotron X-radiation from a singly bent triangular monochromator are derived following a simpler more comparative treatment given in earlier work on reflecting range and prediction of partiality for oscillation camera data [Greenhough & Helliwell (1982). J. Appl. Cryst. 15, 493–508]. In that treatment the possibility of a polychromatic experiment {[see Arndt Nucl. Instrum. Methods (1978), 152, 307–311] for an earlier suggestion} was identified and here the energy profile within each diffraction spot is derived along with the spectral resolution ∂E/E at any point in the profile due to experimental conditions and sample characteristics. A firm theoretical basis is established so that experimental problems and procedures can be discussed with a view to optimizing the method in the light of the presentation of the first reported polychromatic experiment [Arndt, Greenhough, Helliwell, Howard, Rule & Thompson (1982). Nature (London), 298, 835–838].
