DEXTR, or Deep Extreme Cut, obtains an object segmentation from its four extreme points: the left-most, right-most, top, and bottom pixels. The annotated extreme points are given as a guiding signal to the input of the network. To this end, we create a heatmap with activations in the regions of extreme points. We center a 2D Gaussian around each of the points, in order to create a single heatmap
This paper explores the use of extreme points in an object (left-most, right-most, top, bottom pixels) as input to obtain precise object segmentation for images and videos. We do so by adding an extra channel to the image in the input of a convolutional neural network (CNN), which contains a Gaussian centered in each of the extreme points. The CNN learns to transform this information into a. Deep Extreme Cut (DEXTR) This is the implementation of our work Deep Extreme Cut (DEXTR), for object segmentation from extreme points.

Our instance segmentation model is based on the well-known Deep Extreme Cut (DEXTR) approach [3], along with a raster-to-polygon conversion algorithm that yields high quality polygons whose vertices are sampled in a way that reproduces human drawing patterns. The model uses the few clicks provided by human annotators at inference time 【DEXTR】Deep Extreme Cut:From Extreme Points to Object Segmentation.

Deep Extreme Cut (DEXTR) Visit our project page for accessing the paper, and the pre-computed results. This is the implementation of our work Deep Extreme Cut (DEXTR), for object segmentation from extreme points. T DEXTR, or Deep Extreme Cut, is a publicly available object segmentation model for images and videos. We've outlined the DEXTR model and our approach in detail in this post . Many ML methods like DEXTR have been suggested to speed up the process of instance segmentation, but these are not typically tested in a high-scale production. ExtremeNet can be combined with the deep extreme cut (DEXTR) algorithm to conduct segmentation tasks. X. X. Zhou proposed CenterNet (object as points) [ 23 ] in which a detection head was proposed that could work with various networks, such as residual networks (ResNets) [ 26 ], hourglass networks (HourglassNets) [ 27 ], and deep layer.
Given the extreme points of an object, it is trivial to generate the bounding box. If the image is also included, the DEXTR ⁴ algorithm can be used to generate segmentation masks. This makes extreme points much more versatile than bounding boxes Figure 5.Quality vs. annotation budget in video object segmentation: OSVOS performance when trained from the masks of DEXTR or the ground truth, on DAVIS 2016 (left) and on DAVIS 2017 (right). - Deep Extreme Cut: From Extreme Points to Object Segmentatio Ground Truth takes these four points as input and uses the Deep Extreme Cut (DEXTR) algorithm to produce a tightly fitting mask around the object.

With the advent of deep learning, object detection drifted from a bottom-up to a top-down recognition problem Deep Extreme Cut: From Extreme Points to Object Segmentation K.-K. Maninis* S. Caelles J. Pont-Tuset L. Van Gool Computer Vision Lab, ETH Zurich, Switzerland¨ Figure 1. Example results of DEXTR: The user provides the extreme clicks for an object, and the CNN produces the segmented masks Deep extreme cut (DEXTR) [Man+18] is semi-automated tool for object segmentation, requiring four only points to be defined by the user to produce precise results. This manual labeling technique produces bounding boxes using the extreme left, right, top, and bottom points of an object instead of the traditional two-point approach Deep Extreme Cut is a semi-automatic approach characterized by the use of DeeplabV2 with Resnet101, which defines the base network and the need for human boundary point delimitation. Goyal and Yap (2018) promote an automatic Deep Extreme Cut method
We introduce a fully automated 360° video processing pipeline using a hierarchical combination of Artificial Intelligence (AI) modules to create immersive volumetric XR experiences. Two critical productions tasks (person segmentation and depth estimation) are addressed with a parallel Deep Neural Network (DNN) pipeline that combines instance segmentation, person detection, pose estimation.

Management of a patient's body temperature is an important aspect of care that should be addressed by targeted temperature management (TTM). Often, non-invasive methods like forced-air blankets are used. Especially in the operating room this management may be a subsidiary and repetitive task requiring constant observation of the patient's body temperature and adaption using the limited set. Our budget rose from $48 million in FY13 to $65 million in FY14, and a projected $76 million in FY15. But much more important than size, the impact of our work, as evidenced by our Top Outcomes, appears to be stronger than ever. Annual Report 2014 Introduction from World Resources Institute on Vimeo.

A new Gallup poll finds that Americans' opinion of Russia and China have plummeted to historic lows this year, with 79 percent of the population now reporting an unfavorable view of China and 77 percent reporting an unfavorable view of Russia.. The hate predictably falls along partisan lines, with Republicans showing more disfavor toward China and Democrats reserving more of theirs for. The JFK assassination, almost to the day 52 years later, is still subject that generates a lot of emotion, curiosity and speculation. Rightly so - the event was of extreme significance and is a telling reminder that the people who run this world are far above the level of prime ministers and presidents

Turns out, it's a lot easier to cut workers than it is to suddenly hire workers: Before the railroads blame the 33% cut in the workforce on the pandemic, let's point out that by February 2020, just before the pandemic, their headcount had already been cut by 46,000 workers, or by 26%, to 128,000.
