The paper presents a novel algorithm for image quality assessment. First, a simple model of the human visual system, consisting of a nonlinear function and a 2D filter, processes the input images. This filter has one user-defined parameter, whose value depends on the reference image. In the next step, the average value of locally computed correlation(More)
We consider the problem of RF signal analysis where one sensing node observes a frequency band possibly used by multiple packet based radio transmitters. Analysis of the received signal consists of two steps. In the first step we use spectrogram to perform temporal segmentation of the received piecewise statistically homogeneous signal. This task is(More)
We consider a scenario with multiple radio sources performing packet based transmissions. The sources belong to heterogeneous networks and their signals may overlap in time and frequency. Each source is characterized by its power spectral density and an on/off activity sequence. A network of sensors performs measurements, where each sensor computes(More)
We consider a scenario with multiple radio sources operating in the 2.4GHz ISM band and emitting signals that may overlap in time and frequency. Each source is characterized by an on/off signal, which represents its activity in time. Sources are modelled as statistically independent if they belong to different networks or statistically dependent if they(More)
