- Abstract: We present a novel method for proposal free instance segmentation that can
handle sophisticated object shapes which span large parts of an image and form
dense object clusters with crossovers. Our method is based on predicting dense
local shape descriptors, which we assemble to form instances. All instances are
assembled simultaneously in one go. To our knowledge, our method is the first
non-iterative method that yields instances that are composed of learnt shape
patches. We evaluate our method on a diverse range of data domains, where it
defines the new state of the art on four benchmarks, namely the ISBI 2012 EM
segmentation benchmark, the BBBC010 C. elegans dataset, and 2d as well as 3d
fluorescence microscopy data of cell nuclei. We show furthermore that our
method also applies to 3d light microscopy data of Drosophila neurons, which
exhibit extreme cases of complex shape clusters

We introduce a novel technique for processing point clouds that, through a voting procedure, is able to provide an initial estimate of the primitive parameters each type.
By using these estimates we localize the search of the optimal solution in a dimensionally-reduced space, making it efficient to extend the HT to more primitive than those that generally found in the literature.

We present an approach to estimating the continuous 6-DoF pose of an object from a single RGB image.
The approach combines semantic keypoints predicted by a convolutional network (convnet) with a deformable shape model.
We show that our approach can accurately recover the 6-DoF object pose for both instance- and class-based scenarios.

for Biological Images [58.914034295184685]
Instance segmentation is of great importance for many biological applications, such as study of neural cell interactions, plant phenotyping, and quantitatively measuring how cells react to drug treatment.
Box-based instance segmentation methods capture objects via bounding boxes and then perform individual segmentation within each bounding box region.
Our method first detects the center points of the objects, from which the bounding box parameters are then predicted.
The segmentation branch reuses the object features as guidance to separate target object from the neighboring ones within the same bounding box region.
