In the paper a parallel FPGA implementation of the Peer Group Filtering algorithm is described. Implementation details, results, performance of the design and FPGA logic resources are discussed. The PGF algorithm customized for FPGA is compared with the original one and Vector Median Filtering

Real-time Foreground Object Detection Combining the PBAS Background Modelling Algorithm and Feedback from Scene Analysis Module

The article presents a hardware implementation of the foreground object detection algorithm PBAS (Pixel-Based Adaptive Segmenter) with a scene analysis module. A mechanism for static object detection is proposed, which is based on consecutive frame differencing. The method allows to distinguish stopped foreground objects (e.g. a car at the intersection, abandoned luggage) from false detections (so-called ghosts) using edge similarity. The improved algorithm was compared with the original version on popular test sequences from the changedetection.net dataset. The obtained results indicate that the proposed approach allows to improve the performance of the method for sequences with the stopped objects. The algorithm has been implemented and successfully verified on a hardware platform with Virtex 7 FPGA device. The PBAS segmentation, consecutive frame differencing, Sobel edge detection and advanced one-pass connected component analysis modules were designed. The system is capable of processing 50 frames with a resolution of 720 × 576 pixels per second.

Optimisation of the PointPillars network for 3D object detection in point clouds

In this paper we present our research on the optimisation of a deep neural network for 3D object detection in a point cloud. Techniques like quantisation and pruning available in the Brevitas and PyTorch tools were used. We performed the experiments for the PointPillars network, which offers a reasonable compromise between detection accuracy and calculation complexity. The aim of this work was to propose a variant of the network which we will ultimately implement in an FPGA device. This will allow for real-time LiDAR data processing with low energy consumption. The obtained results indicate that even a significant quantisation from 32-bit floating point to 2-bit integer in the main part of the algorithm, results in 5%-9% decrease of the detection accuracy, while allowing for almost a 16-fold reduction in size of the model.Comment: 7 pages, 2 figures, submitted to SPA 2020 conferenc

Etude Comparative De La Croissance Et De La Productivité Chez Le Taro (Colocassia Esculenta L.) Et Le Macabo (Xanthosoma Sagittifolium, Et X Anthosoma Sp) Cultivés Dans Les Conditions Pédoclimatiques De La Ville De Mbaïki (Lobaye) En République Centrafric

Methods: In order to evaluate the growth and production of taro, Colocassia esculenta, macabo, Xanthosoma sp and Xanthosoma sagittifolium varieties, a randomized Fischer block experimental design was set up. The trials were set up in the localities of Mbaïki in the southern part of the Central African Republic. The effects of varieties on growth and production parameters were assessed using analysis of variance (ANOVA) at a classification criterion with Software R version 3.1.3. Results: The vegetative growth and production parameters evaluated showed variability between the different varieties grown. Good vegetative growth was observed in macabo varieties, while in Taro, production was better, with the number of tubers per plant (16.83) and a yield of 13,260 t/ha against 11.42 t/ha and 5.30 t/ha for macabo varieties (V2 and V3). Conclusion: The varieties grown showed high yields except for the macabo variety V3 which had a lower yield than the average for the sub-region. Méthodes.- Dans l’objectif d’évaluer la croissance et la production des variétés de taro, Colocassia esculenta, de macabo, Xanthosoma sp. et European Scientific Journal, ESJ ISSN: 1857-7881 (Print) e - ISSN 1857-7431 January 2021 edition Vol.17, No.3 www.eujournal.org 108 Xanthosoma sagittifolium, un dispositif expérimental en blocs de Fischer randomisé a été mise en place. Les essais ont été installés dans les localités de Mbaïki dans la partie sud de la République Centrafricaine. Les effets de variétés sur les paramètres de croissance et de production ont été appréciés grâce à l’analyse de variance (ANOVA) à un critère de classification avec le Logiciel R version 3.1.3. Résultats.-Les paramètres de croissance végétative et de production évalués ont mis en évidence une variabilité entre les différentes variétés mises en culture. Une bonne croissance végétative a été observée chez les variétés de macabo, tandisque chez le taro, la production a été meilleure, avec le nombre de tubercules par pied (16,83) et un rendement de 13,260 t/ha contre 11.42 t/ha et 5,30t/ha pour les variétés de macabo (V2 et V3). Conclusion.-Les variétés mises en culture ont présenté des rendements élevés excepté la variété de macabo V3 qui a rendement inférieur par rapport à la moyenne de la sous-région

Reliability and Feasibility of the Four Square Step Test for Use in Children with Cerebral Palsy: A Pilot Study

Purpose: The ability to maintain standing balance with a moving base of support and while making rapid postural adjustments is important for independence in various functional activities. Clinical tests and measures have not addressed this ability in children with disability. This pilot study examined the feasibility and reliability of the Four Square Step Test (FSST) as a test of dynamic balance in children with cerebral palsy (CP). Method: Four children with CP (Gross Motor Function Classification Scale levels I-II) were tested on the FSST by 3 assessors on the first occasion (interrater reliability) and repeat-tested by 1 assessor after 2 weeks (test-retest reliability). Six children with typical development (TD) were tested on a separate occasion to explore any between-group difference in performance. Results: The FSST was easy to setup, required no specialized equipment, could be completed in 5 minutes, and might be carried out by clinicians with limited experience in pediatric therapy. It demonstrated excellent interrater reliability (ICC = 0.832) and test-retest reliability (ICC = 0.979) in children with CP. Compared with FSST times for children with TD (mean = 9.12 ± 2.67 seconds), times for children with CP (mean = 18.38 ± 9.02 seconds) were significantly slower (p = 0.019, Mann-Whitney U = -2.345). Conclusions and Recommendations: The pilot study provides initial evidence on the potential usefulness of the FSST as a test of dynamic standing balance in children with CP. This warrants further investigation of the clinimetric properties of the FSST using an adequate sample size
