This paper addresses vision-based people counting under the assumption of an oblique stationary camera setup without any usage of tracking. Our approach is based on motion detection and blob analysis. The estimation of the number of people in the scene is done by accumulating the estimation values of each blob. The blob specific estimation values are computed using four input values: the minimu...

Plasma blob dynamics on the high-field side in the proximity of a magnetic field null (X point) is investigated in TORPEX. A significant acceleration of the blobs towards the X point is observed. Close to the X point the blobs break apart. The E×B drifts associated with the blobs are measured, isolating the background drift component from the fluctuating contribution of the blob internal potent...

PURPOSE Cardiac computed tomography is a rapidly emerging technique for noninvasive diagnosis of cardiovascular diseases. Nevertheless, the cardiac motion continues to be a limiting factor. Electrocardiogram-gated cardiac computed tomography reconstruction methods yield excellent results, but these are limited in their temporal resolution due to the mechanical movement of the gantry, and lead t...

Vannamei shrimp is a species of that has high economic value. In the process trading vaname shrimp, there are different price classes. Determination class based on size shrimp. But in post-harvest process, sorting still done manually, namely by placing white flat table and then separating it so takes long time level accuracy also becomes imprecise, as cultivating coastal area ​​Madura, this due...

In this paper we estimate a sectoral real wage equation for three regional blocs of the enlarged EU that we defined as North (wealthiest EU), South (Greece, Portugal and Spain) and East (acceding Central and Eastern European countries). The estimation results show that real wages react differently in each of the blocs to the impact of market size, location and factor endowments across a range o...

The striate cortex of macaque monkeys contains an array of patches which stain heavily for the enzyme cytochrome oxidase (CO blobs). Cells inside and outside these blobs are often described as belonging to two distinct populations or streams. In order to better understand the function of the CO blobs, we measured the contrast sensitivity and spatial frequency response of single neurons in and a...

The mean-shift algorithm is an efficient technique for tracking 2D blobs through an image. Although it is important to adapt the mean-shift kernel to handle changes in illumination for robot vision at outdoor site, there is presently no clean mechanism for doing this. This paper presents a novel approach for color tracking that is robust to illumination changes for robot vision. We use two inte...

This paper presents an integrated approach for tracking hands, faces and specific facial features (eyes, nose, and mouth) in image sequences. For hand and face tracking, we employ a state-of-the-art blob tracker which is specifically trained to track skin-colored regions. The skin-color tracker is extended by incorporating an incremental probabilistic classifier, which is used to maintain and c...

This paper addresses the problem of object tracking in image sequences. The approach taken is based upon adaptive statistical models. An object selected in a frame by a user is tracked throughout the sequence by using a blob-like description of its features. The object features are continuously updated by using the on-line version of the Expectation-Maximization algorithm. The proposed object d...

Blob trackers have become increasingly powerful in recent years largely due to the adoption of statistical appearance models which allow effective background subtraction and robust tracking of deforming foreground objects. It has been standard, however, to treat background and foreground modelling as separate processes — background subtraction is followed by blob detection and tracking — which ...
