Exemplar-Based Face Parsing Supplementary Material

چکیده
Figures 1 and 2 supplement Figure 4 in our paper. In all cases, the input images come from our Helen [1] test set. We note that our algorithm generally produces accurate results, as shown in Figures 1. However, our algorithm is not perfect and makes mistakes on especially challenging input images, as shown in Figure 2. In our view, the mouth is the most challenging region of the face to segment: the shape and appearance of the lips vary widely from subject to subject, mouths deform significantly, and the overall appearance of the mouth region changes depending on whether the inside of the mouth is visible or not. Unusual mouth expressions, like those shown in Figure 2, are not represented well in the exemplar images, which results in poor label transfer from the top exemplars to the test image. Despite these challenges, our algorithm generally performs well on the mouth, with large segmentation errors occurring infrequently.

متن کاملNot just the norm: exemplar-based models also predict face aftereffects.
The face recognition literature has considered two competing accounts of how faces are represented within the visual system: Exemplar-based models assume that faces are represented via their similarity to exemplars of previously experienced faces, while norm-based models assume that faces are represented with respect to their deviation from an average face, or norm. Face identity aftereffects h...

Towards Open-Universe Image Parsing with Broad Coverage
This paper presents an overview of our work on image parsing, which we define as the problem of labeling each pixel in an image with its semantic category. Our aim is to achieve broad coverage across hundreds of object categories, many of them sparsely sampled. We first describe our baseline nonparametric region-based parsing system. This approach is based on lazy learning, and it can easily sc...
