When Deep Learning Meets Digital Image Correlation

نویسندگان

چکیده

Convolutional Neural Networks (CNNs) constitute a class of Deep Learning models which have been used in the recent past to resolve many problems computer vision, particular optical flow estimation. Measuring displacement and strain fields can be regarded as case this problem. However, it seems that CNNs never so far perform such measurements. This work is aimed at implementing CNN able retrieve from pairs reference deformed images flat speckled surface, Digital Image Correlation (DIC) does. paper explains how called StrainNet developed reach goal, specific ground truth datasets are elaborated train CNN. The main result successfully performs measurements, achieves competing results terms metrological performance computing time. conclusion like offer viable alternative DIC, especially for real-time applications.

When Image Denoising Meets High-Level Vision Tasks: A Deep Learning Approach

Conventionally, image denoising and high-level vision tasks are handled separately in computer vision, and their connection is fragile. In this paper, we cope with the two jointly and explore the mutual influence between them with the focus on two questions, namely (1) how image denoising can help solving high-level vision problems, and (2) how the semantic information from high-level vision ta...

When Semi-supervised Learning Meets Ensemble Learning

Semi-supervised learning and ensemble learning are two important machine learning paradigms. The former attempts to achieve strong generalization by exploiting unlabeled data; the latter attempts to achieve strong generalization by using multiple learners. Although both paradigms have achieved great success during the past decade, they were almost developed separately. In this paper, we advocat...

When image indexing meets knowledge discovery

In our paper, we deal with the challenge of extending automatically the classic image indexing by visual relationship features. The visual relationship features are discovered automatically from images. They contribute to make more efficient the content-based indexing. More particularly, we develop an advanced content-based indexing articulated around the following notions : classic indexing, c...

TensorLog: Deep Learning Meets Probabilistic DBs

We present an implementation of a probabilistic first-order logic called TensorLog, in which classes of logical queries are compiled into differentiable functions in a neuralnetwork infrastructure such as Tensorflow or Theano. This leads to a close integration of probabilistic logical reasoning with deep-learning infrastructure: in particular, it enables high-performance deep learning framework...
