title: Two-point resolution near detection threshold.
abstract: Resolution thresholds were determined for a configuration of two blobs with overlapping Gaussian spatial and temporal envelopes presented near detection-threshold luminance contrast. The resolution thresholds are a constant fraction of the blur parameter of the stimuli over a range of at least two decades. There is no indication for a segmented nature of the resolution discrimination function.
