This work presents an evaluation of different detectors used for the <i>Edge Error</i> measure, which is one of the most used features in Image Quality Assessment (IQA). Among detectors, the proposed <i>Wavelet--based Edge Detector</i> (WEE) is also evaluated. the test is carried out for the quality assessment of images which are distorted by either JPEG,(More)
We derive frame estimates for vector-valued Gabor systems with window functions belonging to Schwartz space. The main result provides frame bound estimates for windows composed of Hermite functions. The proof is based on a recently established sampling theorem for the simply connected Heisenberg group, which is translated to a family of frame estimates via(More)
