Toward real-time polyp detection using fully CNNs for 2D Gaussian shapes prediction

چکیده

• Binary masks may force an F-CNN to use edges as one of the strongest features distinguish polyps, leading generate many false positives with strong edges. 2D Gaussian can be used reduce impact outer during training models by giving less weights. enable F-CNNs sharp and more effectively efficiently detect different types polyps. Experimental results showed that proposed are efficient flat small polyps have unclear boundaries between background polyp parts. MDeNetplus model for automatic detection. The is trained on predict shapes regions in input images. To decrease colon miss-rate colonoscopy, a real-time detection system high accuracy needed. Recently, there been efforts develop detection, but work still required algorithms reliable results. We single-shot feed-forward fully convolutional neural networks (F-CNN) accurate system. usually binary object segmentation. propose instead these number positives. experimental make better effect discriminate from polyp-like method achieved state-of-the-art two datasets. On ETIS-LARIB dataset we 86.54% recall, 86.12% precision, 86.33% F1-score, CVC-ColonDB 91% 88.35% F1-score 89.65%.

Exploring Food Detection Using CNNs

One of the most common critical factors directly related to the cause of a chronic disease is unhealthy diet consumption. In this sense, building an automatic system for food analysis could allow a better understanding of the nutritional information with respect to the food eaten and thus it could help in taking corrective actions in order to consume a better diet. The Computer Vision community...

Real-time damage detection of bridges using adaptive time-frequency analysis and ANN

Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

2D Shapes Classification Using BLAST

This paper presents a novel 2D shape classification approach, which exploits in this context the huge amount of work carried out by bioinformaticians in the biological sequence analysis research field. In particular, in the approach presented here, we propose to encode shapes as biological sequences, employing the widely known sequence alignment tool called BLAST (Basic Local Alignment Search T...

Toward Real-Time SQM for WAAS: Improved Detection Techniques

Signal Quality Monitoring (SQM) algorithms propose to detect anomalous signal distortions primarily through the use of SQM receivers. These receivers employ anywhere from three or more correlator pairs per channel—each slaved to the tracking pair. The measurements from each correlator output can be used to form detection metrics, which are, in general, simple algebraic combinations of the measu...
