Automatic segmentation of skin lesions in clinical images is a very challenging task; it is necessary for visual analysis of the edges, shape and colors of the lesions to support the melanoma diagnosis, but, at the same time, it is cumbersome since lesions (both naevi and melanomas) do not have regular shape, uniform color, or univocal structure. Most of the approaches adopt unsupervised color ...

Estimating plant nitrogen concentration (PNC) has been conducted using vegetation indices (VIs) from UAV-based imagery, but color features have rarely considered as additional variables. In this study, the VIs and moments (color feature) were calculated RGB images, then partial least square regression (PLSR) random forest (RF) models established to estimate PNC through fusing moments. The resul...

The median-of-means is an estimator of the mean a random variable that has emerged as efficient and flexible tool to design robust learning algorithms with optimal theoretical guarantees. However, its use for clustering task suggests dividing dataset into blocks, which may provoke disappearance some clusters in blocks lead bad performances. To overcome this difficulty, procedure termed “bootstr...

In this study, Gaussian white noise and color noise of speech signal are reduced by using adaptive filter and soft computing algorithms. Since the main target is noise reduction of speech signal in a car, ambient noise recorded in a BMW750i is used as color noise in the applications. Signal Noise Ratios (SNR) are selected as +5, 0 and -5 dB for white and color noise. Normalized Least Mean Squar...

In this work, we present the applications of three-dimensional set partitioning methods to the sequence of still color images. The set partitioning methods we use in this paper are SPIHT, a state-of-the-art encoder and SPECK, a more recently developed, low complexity encoder. The three-dimensional versions of these methods are based on the observation that the sequences of images are contiguous...

and Normalized Cut Clustering Jui-Chen Wu, Jun-Wei Hsieh * , Yung-Sheng Chen, and Cheng-Min Tu Department of Electrical Engineering Yuan Ze University, Taiwan *[email protected] Abstract This paper proposes a novel approach for vehicle orientation detection using “vehicle color” and edge information based on clustering framework. To extract the “vehicle color”, this paper proposes a novel...

In order to develop new-typed multifunctional nanocomposites, fluorescent-electrical-magnetic trifunctional coaxial nanoribbons with tunable fluorescent color, including white-light emission, have been successfully fabricated via coaxial electrospinning technology. Each stripe of coaxial nanoribbon is composed of a Fe3O4/PMMA core and a [Eu(BA)3phen+Dy(BA)3phen]/PANI/PMMA (PMMA = polymethyl met...

The performance of a prototype opaque-type colored silicon-based solar cell integrated with liquid crystalline cholesteric layers is investigated. These devices were developed using only organic components and wet processes, without complicated vacuum processes. evaluated performances the cells inferior to those other types previously reported because inherent limitations layers, such as limite...
