We propose an improved algorithm based on fractal dimension and third-order characterization to detect dim target with cluttered background in an infrared (IR) image. We also illustrate the performance and efficiency comparisons between the presented algo
Erbium-doped glass showing the wider 1.5-um emission band is reported in a novel oxide system TeO_{2}-WO_{3}-Nb_{2}O_{5} and their thermal stability and optical properties such as absorption, emission spectra, cross-sections and fluorescence lifetime were
