- Abstract summary: Our method divides the image into several regions that capture important textures or semantics and selects a representative pixel from each region to store.
We propose two smooth tensor completion algorithms that can effectively reconstruct different types of images from the selected pixels.

- Abstract: This paper presents a pixel selection method for compact image representation
based on superpixel segmentation and tensor completion. Our method divides the
image into several regions that capture important textures or semantics and
selects a representative pixel from each region to store. We experiment with
different criteria for choosing the representative pixel and find that the
centroid pixel performs the best. We also propose two smooth tensor completion
algorithms that can effectively reconstruct different types of images from the
selected pixels. Our experiments show that our superpixel-based method achieves
better results than uniform sampling for various missing ratios.

Community detection is a powerful tool from complex networks analysis that finds applications in various research areas.
Superpixels aim at representing the image at a smaller level while preserving as much as possible original information.
We study the efficiency of superpixels computed by state-of-the-art community detection algorithms on a 4-connected pixel graph.

Clustering [57.76302397774641]
We consider each representative region with independent semantic information as a subspace, and formulate superpixel segmentation as a subspace clustering problem.
We show that a simple integration of superpixel segmentation with the conventional subspace clustering does not effectively work due to the spatial correlation of the pixels.
We propose a novel convex locality-constrained subspace clustering model that is able to constrain the spatial adjacent pixels with similar attributes to be clustered into a superpixel.
