A paper was accepted as oral presentation at the International Conference on Computer Vision (ICCV) 2015:
Christian Bailer, Bertram Taetz, Didier Stricker
Flow Fields: Dense Correspondence Fields for Highly Accurate Large Displacement Optical Flow Estimation
ICCV is one of the premier conferences for researchers in the field of computer vision.
The conference will be held from December 11th to September 18th in Santiago (Chile).
We are delighted to announce the winning of smartDoc competition (challenge 2) as part of the competitions in ICDAR 2015 Conference.
The goal of the competition is to extract the textual content from document images which are captured by mobile phones. The images are taken under varying conditions to provide a challenging input (full description of the challenge).
The method is based on “Combining Clustering and Classfication Results” (CCC); initially the background color is used to first detect and dewarp the document. The image is then binarized to extract lines, words and subwords. Those are then clustered incrementally across all the corpus. A 1D LSTM is trained on both sharp and blurry gray-scale text-lines for recognizing subwords. Clusters of subwords are labeled by majority voting.
Each year an expert jury from the University of Kaiserslautern is nominating outstanding doctoral theses for several academic subjects together with the Kreissparkasse Kaiserslautern..
We congratulate Dr.-Ing. Petersen on winning this award for Computer Science.
This award was granted for his doctoral thesis that deals with the understanding of manual workflows from video examples. An important application of his research work is the automatic generation of interactive Augmented Reality manuals from the observation of a reference performance.
Workflow knowledge comprises both explicit, verbalizable knowledge and implicit knowledge, which is acquired through practice. Learning a complex workflow therefore benefits from training with a permanent corrective. Augmented Reality manuals that display instructive step-by-step information directly into the user’s field of view provide an intuitive and provably effective learning environment. However, their creation process is rather work intensive and current technological approaches lead to insufficient interactivity with the user. In this thesis we present a comprehensive technical approach to algorithmically analyze manual workflows from video examples and use the acquired information to teach explicit and implicit workflow knowledge using Augmented Reality. The technical realization starts with unsupervised segmentation of single work steps and their categorization into a coarse taxonomy. Thereafter, we analyze the single steps for their modalities using a hand and finger tracking approach optimized for this particular application. Using explicit, work step specific generalization we are able to compensate for morphological differences among different users and thus to reduce the need for large amounts of training data. To render this information communicable, i.e., understandable by a different person, we present the further processed data using Augmented Reality as an interactive tutoring system. The resulting system allows for fully or semi-automatic creation of Augmented Reality (AR-) manuals from video examples as well as their context-driven presentation in AR. The method is able to extract and to teach procedural, implicit workflow knowledge from given video examples. In an extensive evaluation, we demonstrate the applicability of all proposed technical components for the given task.
Prof. Didier Stricker gave a key impulse talk about „Technologiy and Innovation“ in the area of Digital Technology at the MIT:Futura. The event analyzed barriers for digitalization, creation of start-ups and large capital investment in Germany. Investors, founders and European Commissar for Digitalization – Mr Oettinger – discussed current situation and possible changes for speeding-up technological changes at economical and societal level.
The new spin-off of the department Augmented Vision of DFKI won the prestigious start-ups ICT price of the Ministry of Economy.
The team of 4 formers members of the department were congratulated at the Cebit fair 2015.
