Recurrent Exposure Generation for Low-Light Face Detection

Abstract: Face detection from low-light images is challenging due to limited photons and inevitable noise, which, to make the task even harder, are often spatially unevenly distributed. A natural solution is to borrow the idea from multi-exposure, which captures multiple shots to obtain well-exposed images under challenging conditions. High-quality implementation/approximation of multi-exposure from a single image is however nontrivial. Fortunately, as shown in this paper, neither is such high-quality necessary since our task is face detection rather than image enhancement. Specifically, we propose a novel Recurrent Exposure Generation (REG) module and couple it seamlessly with a Multi-Exposure Detection (MED) module, and thus significantly improve face detection performance by effectively inhibiting non-uniform illumination and noise issues. REG produces progressively and efficiently intermediate images corresponding to various exposure settings, and such pseudo-exposures are then fused by MED to detect faces across different lighting conditions. The proposed method, named REGDet, is the first ‘detection-with-enhancement’ framework for low-light face detection. It not only encourages rich interaction and feature fusion across different illumination levels, but also enables effective end-to-end learning of the REG component to be better tailored for face detection. Moreover, as clearly shown in our experiments, REG can be flexibly coupled with different face detectors without extra low/normal-light image pairs for training. We tested REGDet on the DARK FACE low-light face benchmark with thorough ablation study, where REGDet outperforms previous state-of-the-arts by a significant margin, with only negligible extra parameters.

On Thompson's inverted-face phenomenon (research note).

Abstract: By now it is probably safe to say that everyone who works in the field of perception and many others as well have seen the dramatic illustration of the inverted face of Margaret Thatcher published by Thompson (1980). The mouth and the eyes are in fact upright within the inverted picture and yet, when the picture is upside down, it simply looks like an inverted picture. However, when the picture is rotated through 180° so that the face is upright, the now inverted features render the face grotesque. The grotesqueness obviously derives from the inverted features within an otherwise upright face. Another example is shown in figure 1. The critical theoretical point is that one does not notice the uprightness of isolated features when looking at the inverted face. Why is this? The answer to this question requires consideration of the question why it is not merely difficult but essentially impossible to correct for or mentally rotate an inverted face in such a way that we can perceive the expression or, in many cases, identify the face. The difficulty occurs even when the picture is upright in the environment and we view it from an inverted body position (as in bending over and looking between our legs). This last observation makes clear that the difficulty is one that concerns inversion of the image on the retina, an egocentric inversion, rather than inversion with respect to

Abstract: that the erosion of the Westphalian state system has led to a large-scale re-evaluation of the trade-off between peace and justice that made the Treaty of Westphalia possible in the first place. Hutchings contribution to the IR literature is welcome (though it would have benefited from a few commentators from outside the United States), if for no other reason than that the term 'post-cold war era' sounds increasingly like the beginning of the post-Westphalian era in a very tangible sense.

Creating a Just Future: The Politics of Peace and the Ethics of Creation in a Threatened World

Abstract: Here is Moltmann discussing the questions that matter more than any others for our world: How is it possible to create a world society worth living in? What positive contribution can Christians make in the face of the nuclear threat? What can be done to mobilize concern for the future of the environment and its natural resources? Moltmann provides a new combination of insights from the Bible and from oriental religion as he has come to know it through his work in the Far East to produce some fresh and challenging perspectives on the primary global issues of our time.
