We rely on our visual system to cope with the vast barrage of incoming light patterns and to
extract features from the scene that are relevant to our well-being. The necessary reduction …

With the multifocal technique, as developed by Erich Sutter and colleagues, scores of focal
electroretinogram (ERG) responses can be obtained in a matter of minutes. Although this …

In this paper, we present a new video database: CVD2014-Camera Video Database. In
contrast to previous video databases, this database uses real cameras rather than …

Within natural images there is substantial spatial variation in both local contrast and local
luminance. Understanding the statistics of these variations is important for understanding the …

The asynchronous time-based neuromorphic image sensor ATIS is an array of
autonomously operating pixels able to encode luminance information with an exceptionally …

Foveated rendering adapts the image synthesis process to the user's gaze. By exploiting the
human visual system's limitations, in particular in terms of reduced acuity in peripheral …

We see over an enormous range of mean light levels, greater than the range of output
signals retinal neurons can produce. Even highlights and shadows within a single visual …

The first stage of color vision is now well understood (see Chap. 10). When presented in the
same context under photopic conditions, pairs of lights that produce the same excitations in …

Visual responses are known to depend on stimulus contrast and not simply on the absolute
levels of retinal illumination. Here, we have determined the contrasts that mammalian retinal …

We present a tone mapping algorithm that is derived from a model of retinal processing. Our
approach has two major improvements over existing methods. First, tone mapping is applied …
