Query: ADCC: An Effective and Intelligent Attention Dense Color Constancy
  System for Studying Images in Smart Cities   As a novel method eliminating chromatic aberration on objects, computational
color constancy has becoming a fundamental prerequisite for many computer
vision applications. Among algorithms performing this task, the learning-based
ones have achieved great success in recent years. However, they fail to fully
consider the spatial information of images, leaving plenty of room for
improvement of the accuracy of illuminant estimation. In this paper, by
exploiting the spatial information of images, we propose a color constancy
algorithm called Attention Dense Color Constancy (ADCC) using convolutional
neural network (CNN). Specifically, based on the 2D log-chrominance histograms
of the input images as well as their specially augmented ones, ADCC estimates
the illuminant with a self-attention DenseNet. The augmented images help to
tell apart the edge gradients, edge pixels and non-edge ones in log-histogram,
which contribute significantly to the feature extraction and color-ambiguity
elimination, thereby advancing the accuracy of illuminant estimation.
Simulations and experiments on benchmark datasets demonstrate that the proposed
algorithm is effective for illuminant estimation compared to the
state-of-the-art methods. Thus, ADCC offers great potential in promoting
applications of smart cities, such as smart camera, where color is an important
factor for distinguishing objects.
