In this paper we address the problem of object detection in cluttered scenes. Local image features and their spatial configuration act as representation of object classes which are learned in a discriminative fashion. Recent contributions in the area of object detection indicate the importance of using geometrical properties for representing object classes. Prompted by this, we devised an approach tailored to control the importance of the features and their spatial alignment. We quantitatively show that modeling the spatial distribution of local features and optimising the influence of both cues significantly boosts object detection performance.
An important issue in the analysis of two-dimensional electrophoresis images is the detection and quantification of protein spots. The main challenges in the segmentation of 2DGE images are to separate overlapping pro...

A control method for small domestic power plants using renewable energy is described in this paper. This method is not only capable of optimizing the working point of the plant but also implements active power factor correction and lowers the extant harmonic distortion in the line. The novel element in the proposed complex controller structure is the upper harmonic controller that minimizes the amplitudes of the 3rd, 5th 7th, 9th, and the 11th upper harmonic component in the output voltage. The proposed controller has been investigated by simulation in Matlab environment, and as a result, substantial improvement of the output voltage and current waveform could be achieved. Robustness of the method against nonlinear loads has also been tested.
