March 2017 edition – Vol.9 no.3


Our management team is preparing to publish the 2016 annual report, the annual symposium in May, and the annual general meeting of members to adjust the focus in our practices and work. In addition, we have four renowned speakers from a variety of international research centers, three of which are distinguished lecturers elected by either IEEE Solid-State Circuits Society or IEEE Circuits and Systems Society (seminars, ReSMiQ symposium). We serve our members and promote conditions for student researchers to foster their abilities to innovate.

On 22nd March, the Symposium of the Electronic Industry Group (RIE) entitled “Electronics for the People” was held at Polytechnique Montréal. The RIE aims to bring together manufacturers, service companies and partners who demonstrate their intention to promote and contribute to the objectives of the corporation and to stimulate the Québec industry. ReSMiQ was a partner of this event and several of its members participated as speakers and panelists. Gabriela Nicolescu of Polytechnique Montréal presented the conference “Modeling and analysis of 3D multiprocessors on chip for the future cloud computing” and Mohamad Sawan of Polytechnique Montréal presented the closing conference “Intelligent medical devices: industrial opportunities and rewarding research” . Daniel Massicote of the UQTR was invited to participate in the roundtable “Carrier niches for the electronics industry: How to access it? “. The symposium participants were invited to visit the PolyFab laboratory. More details

Red Lesion Detection Using Dynamic Shape Features
for Diabetic Retinopathy Screening

The development of an automatic telemedicine system for computer-aided screening and grading of diabetic retinopathy depends on reliable detection of retinal lesions in fundus images. In this paper, a novel method for automatic detection of both microaneurysms and hemorrhages in color fundus images is described and validated. The main contribution is a new set of shape features, called Dynamic Shape Features that do not require precise segmentation of the regions to be classified. These features represent the evolution of the shape during image flooding and allow discriminating between lesions and vessel segments. The method is validated per-lesion and per-image using six databases, four of which are publicly available. It proves to be robust with respect to variability in image resolution, quality, and acquisition system. On the Retinopathy Online Challenge's database, the method achieves a FROC score of 0.420 which ranks it fourth. On the Messidor database, when detecting images with diabetic retinopathy, the proposed method achieves an area under the ROC curve of 0.899, comparable to the score of human experts, and it outperforms state-of-the-art approaches.

Examples of lesion detection. The top row shows the Gp images (dark lesions). The bottom row shows the detected lesions. The probability threshold is set to 0.24, corresponding to 51% per-lesion sensitivity and an average of 3.3 FPI. True positives are filled in red or marked by a red square. False positives are circled in green. Sample false negatives are marked by blue triangles.
