A computer-implemented method, and corresponding system, predicts existence of a feature in a scene within an environment for each of at least two modes of observation, e.g., thermal, video color, or multispectral imaging, of the scene. Predicting the existence includes calculating a proposal of the existence of the feature within a respective bounded region of a representation of the scene for each of the at least two modes of each observation of a sequence of observations. The method uses a projection function that synergistically shares information between or among the at least two modes to generate a corresponding fused predicted existence of the feature for each of the at least two modes of each observation, thereby maximizing the benefits of multi-modality. The feature may be an object of interest that may be occluded and moving within the environment. The predicted existence enables the object to be detected, tracked, and / or identified.
