The trade‐off between accuracy and the complexity of real‐time background subtraction

IET Image Processing, 2021
Background subtraction used in object detection, tracking and action recognition is a typical method that separates foreground objects from the background. These applications require accuracy and a complexity reduction technique.

Infrared Structure at NNLO Using Antenna Subtraction [PDF]

, 2013
We consider the infrared structure of hadron-hadron collisions at next-to-next-to leading order using the antenna subtraction method. The general form of the subtraction terms is presented for double real, real-virtual and double virtual contributions.

Study of stochastic estimates of quark loops with unbiased subtraction [PDF]

, 2002
Stochastic noise estimator method is a powerful tool to calculate the disconnected insertion involving quark loops. We study the variance reduction technique with unbiased subtraction. We use the complex $Z_2$ noise to calculate the quark loops on a $16^3 \times 24$ lattice with $\beta = 6.0$ and $\kappa$ = 0.154.

Fingerprint Spectrophotometric Methods for the Determination of Co-Formulated Otic Solution of Ciprofloxacin and Fluocinolone Acetonide in Their Challengeable Ratio

Journal of Analytical Methods in Chemistry, 2019
Six spectrophotometric methods were developed to determine a new single-dose otic solution known as “Otovel®,” which consists of two components: the major one is ciprofloxacin (CIP) and the minor is fluocinolone acetonide (FLU).

Comparison between subtraction and dynamic MRI in assessing treatment response following radiofrequency ablation in patients with hepatocellular carcinoma

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Hepatocellular carcinoma (HCC) is one of the most prevalent cancers worldwide, and if left untreated, one of the most lethal. Ablative therapies including radiofrequency ablation (RFA) play increasingly important role for patients with liver ...
