Fuzzy c-means (FCM) clustering with spatial constraints has attracted great attention in the field of image segmentation. However, most of the popular techniques fail to resolve misclassification problems due to the inaccuracy of their spatial models. This paper presents a new unsupervised FCM-based image segmentation method by paying closer attention to the selection of local information. In this...
We report the design and fabrication of tapered photonic crystal fibers for efficient fceo detection and ultra-flat visible super-continuum generation, which are used in an astro-comb system.
Tapered photonic crystal fiber was designed and fabricated to support an octave spanning supercontinuum generation, directly pumped by an 500 MHz Yb:fiber oscillator. More than 40dB fceo signals were detected and locked.
In order to overcome the poor anti-noise performance of traditional fuzzy C-Means (FCM) algorithm in image segmentation, a novel improved FCM algorithm was proposed in this paper based on Particle Swarm Optimization (PSO) algorithm and Markov Random Field (MRF) model, which can make full use of the global searching ability of PSO and the spatial information integrating ability of MRF for image segmentation...
