Wallflower (Erysimum cheiri (L.) Crantz) is a common medicinal plant in Persian medicine and nowadays some traditional products from wallflower are consumed on global markets. The aim of the present study was to study the phytochemical constituents of wallflower and discuss safety evaluations related to the traditional wallflower preparations. Major Persian scholars (e.g. Avicenna) boo...

Anal fissure is an ischemic ulcer that occurs in anoderm and it has no obvious etiology and pathophysiology in current medicine. Anal fissure has a profound history in Persian and Persian medicine and wallflower (Erysimum cheiri (L.) Crantz) has been a common medication in this case. Traditional oil and/or dilute decoction of wallflower has been introduced as an effective topical medic...

Background maintenance is a frequent element of video surveillance systems. We develop Wallflower, a threecomponent system for background maintenance: the pixellevel component performs Wiener filtering to make probabilistic predictions of the expected background; the region-level component fills in homogeneous regions of foreground objects; and the frame-level component detects sudden, global c...

Sandra M. Duval Mark A. Berhow New Crops and Processing Technology Research, USDA, ARS, National Center for Agricultural Utilization Research, 1815 North University Street, Peoria, IL 61604 Defatted seedmeals from 15 glucosinolate-containing plant species were analyzed for herbicidal activity by determining inhibition of seedling emergence when added to a sandy loam soil containing wheat and si...

Subspace learning methods are widely used in background modeling to tackle illumination changes. Their main advantage is that it doesn’t need to label data during the training and running phase. Recently, White et al. [1] have shown that a supervised approach can improved significantly the robustness in background modeling. Following this idea, we propose to model the background via a supervise...

An extensive literature on reputation signaling has focused on the desire for positive reputation. In our paper we provide experimental evidence that some individuals are averse to any form of reputation; this aversion correlates with gender in a prosocial setting. We formalize our hypotheses of these “wallflower” types in a theoretical model. Our experimental results are consistent with the mo...

Mixture of Gaussians (MOG) has been widely used for robustly modeling complicated backgrounds, especially those with small repetitive movements (such as leaves, bushes, rotating fan, ocean waves, rain). The performance of MOG can be greatly improved by tackling several practical issues. In this paper, we quantitatively evaluate (using the Wallflower benchmarks) the performance of the MOG. with ...

This paper introduces an advanced codebook model for foreground-background segmentation. The improvement is two-fold. First, to cope with changing global lumination, we develop the conventional codebook with confidence functions. Similarities of both brightness and normalized color-vector are integrated confidence-weightedly to form overall similarity. A designed codeword-update progress also c...
