+ | ===== RoboSherlock -- Framework for Cognitive Perception ===== | ||
+ | |||
+ | RoboSherlock is a common framework for cognitive perception, based on the principle of unstructured information management (UIM). UIM has proven itself to be a powerful paradigm for scaling intelligent information and question answering systems towards real-world complexity (i.e. the Watson system from IBM). Complexity in UIM is handled by identifying (or hypothesizing) pieces of | ||
+ | structured information in unstructured documents, by applying ensembles of experts for annotating information pieces, and by testing and integrating these isolated annotations into a comprehensive interpretation of the document. | ||
+ | |||
+ | RoboSherlock builds on top of the ROS ecosystem and is able to wrap almost any existing perception algorithm/ | ||
+ | |||

+ | ===== Proposed Topics ===== | ||

+ | In the following, we list our proposals for the Google Summer of Code topics that contribute to the aforementioned open-source projects. | ||

+ | **Main Objective: | ||
+ | able robots in a human environment to recognize objects in diffi- | ||
+ | cult and challenging scenarios. To achieve this the participant will | ||
+ | develop annotators for RoboSherlock that are particularly aimed at | ||
+ | object-hypotheses generation and merging. Generating a hypotheses | ||
+ | essentially means to generate regions/ | ||
+ | form a single object or object-part. In particular this entails the de- | ||
+ | velopment of segmentation algorithms | ||
+ | or object properties, as the likes of transparent objects, or cluttered, | ||
+ | occluded scenes. The addressed scenarios include stacked, occluded | ||
+ | objects placed on shelves, objects in drawers, refrigerators, | ||
+ | ers, cupboards etc. In typical scenarios, these confined spaces also | ||
+ | bare an underlying structure, which will be exploited, and used as | ||
+ | background knowledge, | ||
+ | show up as parallel lines using an edge detection). Specifically we | ||
+ | would start from (but not necessarly limit ourselves to) the implemen- | ||
+ | tation of two state-of-the-art algorithms described in recent papers: | ||
+ | |||
+ | [1] Aleksandrs Ecins, Cornelia Fermuller and Yiannis Aloimonos, Cluttered Scene Segmentation Using the Symmetry Constraint, International Conference on Robotics and Automation(ICRA) 2016 | ||
+ | [2] Richtsfeld A., M ̈ | ||
+ | orwald T., Prankl J., Zillich M. and Vincze | ||
+ | M. - Segmentation of Unknown Objects in Indoor Environments. | ||
+ | IEEE/RSJ International Conference on Intelligent Robots and Sys- | ||
+ | tems (IROS), 2012. | ||
+ | |||
+ | **Task Difficulty: | ||
+ | |||
+ | **Requirements: | ||
+ | |||
+ | **Expected Results:** Currently the RoboSherlock framework lacks good perception algorithms that can generate object-hypotheses in challenging scenarios(clutter and/or occlusion). The expected results are several software components based on recent advances in cluttered scene analysis that are able to successfully recognized objects in the scenarios mentioned in the objectives, or a subset of these. | ||
