Noisy iris smoothing and segmentation scheme based on improved Wildes method.
Kumawat A, Panda S. Kumawat A, et al. Multidimens Syst Signal Process. 2023;34(1):47-79. doi: 10.1007/s11045-022-00852-w. Epub 2022 Sep 28. Multidimens Syst Signal Process. 2023. PMID: 36185099 Free PMC article.
To overcome these problems, we have proposed an improved Wildes method (IWM) for segmentation in iris recognition system. The proposed algorithm consists of two major steps before applying Wildes method for segmentation: edge detection of iris and pupi …

Multispectral images of flowers reveal the adaptive significance of using long-wavelength-sensitive receptors for edge detection in bees.
Vasas V, Hanley D, Kevan PG, Chittka L. Vasas V, et al. J Comp Physiol A Neuroethol Sens Neural Behav Physiol. 2017 Apr;203(4):301-311. doi: 10.1007/s00359-017-1156-x. Epub 2017 Mar 17. J Comp Physiol A Neuroethol Sens Neural Behav Physiol. 2017. PMID: 28314998 Free PMC article.
A crucial first step in recognition is the identification of edges and the segmentation of the visual field into areas that belong together. Honeybees and bumblebees acquire visual information through three types of photoreceptors; however, they only use a si …
