    DURING THE PAST two decades the consideration of multiple objectives in modeling and decisionmaking has grown by leaps and bounds. The seventies in particular have seen the emphasis shift from the dominance of single-objective modeling and optimization toward an emphasis on multiple objectives. This has led to the emergence of a new field that has come to be known as multiple-criteria decisionmaki... View full abstract»

    Publication Year: 1985, Page(s):343 - 351
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1881 KB)

    Neural encoders translate information on the time-varying intensity of stimuli into sequences of membrane depolarization spikes. Their output can be considered the realization of a stochastic point process, the overall encoder behaviour being characterized through ensemble-averaged responses to identical stimuli and environmental conditions. A new mathematical model for the coding process is prese... View full abstract»

    A number of adaptive estimators to restore images degraded by signal-dependent film grain noise have been derived. These estimators are characterized by their ability to adapt to the nonstationary properties of the image signal distribution. This adaptability results in restored images with better contrast and noise suppression properties when compared with nonadaptive estimators. Lookup tables we... View full abstract»
