Query: Revisiting Dilated Convolution: A Simple Approach for Weakly- and Semi-
  Supervised Semantic Segmentation   Despite the remarkable progress, weakly supervised segmentation approaches
are still inferior to their fully supervised counterparts. We obverse the
performance gap mainly comes from their limitation on learning to produce
high-quality dense object localization maps from image-level supervision. To
mitigate such a gap, we revisit the dilated convolution [1] and reveal how it
can be utilized in a novel way to effectively overcome this critical limitation
of weakly supervised segmentation approaches. Specifically, we find that
varying dilation rates can effectively enlarge the receptive fields of
convolutional kernels and more importantly transfer the surrounding
discriminative information to non-discriminative object regions, promoting the
emergence of these regions in the object localization maps. Then, we design a
generic classification network equipped with convolutional blocks of different
dilated rates. It can produce dense and reliable object localization maps and
effectively benefit both weakly- and semi- supervised semantic segmentation.
Despite the apparent simplicity, our proposed approach obtains superior
performance over state-of-the-arts. In particular, it achieves 60.8% and 67.6%
mIoU scores on Pascal VOC 2012 test set in weakly- (only image-level labels are
available) and semi- (1,464 segmentation masks are available) supervised
settings, which are the new state-of-the-arts.
