In this paper, we propose a new region extraction method with a chromakey technique using a two-tone striped background. A chromakey compositing is a technique for separating actors or actresses from a background, and then compositing a different background. The conventional chromakey technique usually uses an unicolored blue or green background, and has a problem that one’s clothes are regarde...
Performing foreground / background segmentation in outdoor scene is very challenging. Starting from a stateof-the-art color-based approach [8], we propose three improvements: the use of the YCoCg color space, a spherical association volume, and a cast shadows management approach. Using image sequences with ground truth at pixel-level, we quantitatively measured the performances of the proposed ...
Depth information has been used in computer vision for a wide variety of tasks. Since active range sensors are currently available at low cost, high-quality depth maps can be used as relevant input for many applications. Background subtraction and video segmentation algorithms can be improved by fusing depth and color inputs, which are complementary and allow one to solve many classic color seg...
بررسی فرایند الکتروفنتون به منظور تصفیه ی پساب شرکت پتروشیمی شازند و بهینه سازی عوامل موثر بر فرایند
هدف از این تحقیق بررسی کارایی فرایند الکتروفنتون و بهینه سازی پارامترهای موثر بر فرایند به کمک طراحی آماری به منظور تصفیه پساب شرکت پتروشیمی شازند میباشد.در این تحقیق تاثیر پارامترهای : زمان واکنش ، چگالی جریان، ph پساب ، نسبت (?ml h?_2 o_2)/( lit pw) و نسبت مولی (mol h_2 o_2)/(mol fe^(2+) ) بر حذف cod و color از پساب پتروشیمی تحت فرایند الکتروفنتون( با الکترود های آهن و آلومینیوم به طور جداگان...
Color Correction for Multi-view Video Based on Background Segmentation and Dominant Color Extraction
Color correction is a necessary operation in multi-view video processing, because color tends to be influenced by camera characteristic, surface reflectance or scene illumination. To achieve high-quality correction results, a new color correction method, based on the theoretical model of multi-view imaging and image restoration, is proposed in this paper. Considering the illumination problem in...
