This paper applies the boosting classifier proposed by Viola and Jones to the detection of impact craters on the surface of Mars. The performance of the boosting algorithm is comparable to the best algorithms described in the literature.

The paper discusses the Sonata for Viola and Piano op. 147 (1975) by Dmitri Shostakovich in order to generalize aspects of its instrumental chamber stylistics. performance version Fyodor Druzhynin (viola) Mikhail Muntyan (piano), who were first performers this musical piece, was analyzed. Their interpretation may be considered golden standard, as precise possible author’s idea. dedicated his op...

A good image object detection algorithm is accurate, fast, and does not require exact locations of objects in a training set. We can create such an object detector by taking the architecture of the Viola-Jones detector cascade and training it with a new variant of boosting that we call MILBoost. MILBoost uses cost functions from the Multiple Instance Learning literature combined with the AnyBoo...

Object detection is a very active research area in the eld of computer vision. A number of machine learning techniques have been applied to the problem with varying degrees of succes. The early implementations used arti cial neural networks, while recently most apporaches have explored boosting simple features. Viola and Jones were extremely successful in this approach, their paper is one of th...

Viola and Jones [1] proposed the influential rapid object detection algorithm. They used AdaBoost to select from a large pool a set of simple features and constructed a strong classifier of the form {j αjhj(x) ≥ θ} where each hj(x) is a binary weak classifier based on a simple feature. In this paper, we construct, using statistical detection theory, a binary decision tree from the strong classi...

Face detection and tracking are of the most challenging problems of the object tracking field because of the large variability of faces and facial expressions. In this paper, two different algorithms for face tracking based on unscented Kalman filter (UKF) are proposed. The first proposed algorithm is UKF based on Viola-Jones algorithm. Viola-Jones is extremely fast feature computation, efficie...

In this paper, we present a framework for robust people detection in low resolution image sequences of highly cluttered dynamic scenes with non-stationary background. Our model utilizes appearance features together with shortand long-term motion information. In particular, we boost Integral Gradient Orientation histograms of appearance and short-term motion. Outputs from the detector are mainta...

This study was aimed to obtain polyploid plants of viola (Viola acuminata Ledebour) using the antimitotic agent colchicine. Experiments consisted in using colchicine on ungerminated seeds. The seeds were plunged into colchicine solutions in concentrations of 0.01, 0.05, 0.10 and 0.20% for 24 and 48 h. Polyploidy levels (diploid, tetraploid and hexaploid) were firstly detected by chromo...
