Transformer-Based Disease Identification for Small-Scale Imbalanced Capsule Endoscopy Dataset

Vision Transformer is emerging as the best computer vision specialist in the market with its outstanding results in several tasks. On a small-scale imbalanced capsule endoscopic image database, it's difficult for us to use ViT to train from scratch. We started from scratch on two publicly available datasets for capsule endoscopy disease classification, with 79. 15% accuracy on the Kvasir-Capsule dataset and 98. 63% accuracy on the Red Lesion Endoscopy classification task.

Machine learning techniques to detect bleeding frame and area in wireless capsule endoscopy video

This study demonstrates a new method to color extraction to distinguish bleeding frames from those that are not normal ones and locate more bleeding areas. To get the clustered centers that define WCE photos as words, we use complete color information on the WCE photographs and the pixel-based clustering strategy. To produce a first-stage salience map, we show two-step instructions for extracting saliency maps to highlight bleeding locations with a distinct color channel mixer. Following a safe fusion strategy and threshold, we find bleeding spots on the second stage salience map, which was captured with optical contrast.

Deep convolutional neural networks for filtering out normal frames in reviewing wireless capsule endoscopy videos

The ability to non-invasively visualize the gastrointestinal tract with high quality has been provided by Abstract Wireless capsule endoscopy. We have created six deep convolutional neural networks in this report to answer the demand for high classification precision and high NPV. We discovered that the new architectures could avoid mislabeling new pathologies that weren't included in the training database, which leads to generalization of NPV. These new pathologies, including Ulcer, Erosion, Polyp, Blood, Erythematous, and Lymphoid hyperplasia, are among patients that are related to the latest networks in order to determine the generalization accuracy of the Normal class's blood vessels. DN_BFCG demonstrated the highest generalization accuracy for all new pathologies in the initial analysis, indicating that the decision boundary for Normal class is stable and generalizable.

Colon Capsule Endoscopy in the Diagnosis of Colon Polyps: Who Needs a Colonoscopy?

Colon screening services have reduced colon cancer mortality. A number of carefully controlled studies have all agreed that second-generation capsule endoscopy has excellent sensitivity for polyp detection and a high negative predictive value. The clinician with a decision on the threshold for colonoscopy referral is the clinician who examines CT colonography, capsule screening results, leaving the clinician with a decision on the threshold for colonoscopy referral. Overall, colon capsules are an essential tool in polyp identification and colon screening, as well as a filter that determines who needs a colonoscopy. u201d.

Low-Power Low-Area Near-Lossless Image Compressor for Wireless Capsule Endoscopy

The compressor physically processes the raw data from the Bayer Color Filter Array imager to minimize the costly of color interpolation. The compressor's main part, i. e. , the entropy encoder, uses the existing correlations between the color components of a captured CFA image to enhance the compressor's effectiveness in terms of energy consumption, silicon area, and compression ratio. The proposed image compressor only needs 12. 4% of the memory required by other high-quality CFA compressors based on the JPEG-LS framework. Despite this significant decrease in memory size, the proposed image compressor outperforms other state-of-the-art coding schemes on capsule endoscopy images. Using two different low-cost CMOS processes, the proposed image compressor has been used as an intellectual property core. The IP core has been used in the TSMC 130 nm CMOS process, resulting in higher energy savings and increased energy savings.

An Efficient Gastrointestinal Hemorrhage Detection and Diagnosis Model for Wireless Capsule Endoscopy

Endoscopy captures a portion of human gastrointestinal tract that is otherwise unobtainable by traditional endoscopy experiments. For extracting the GI images's features, an effective Normalized Gray Level Co-occurrence Matrix is used. The processing GI images were classified by Then, a kernel support vector machine with particle swarm optimization is used for the classification of the processed GI images. The results revealed the improved classification outcome of the presented model on all of the applied images under various conditions.

Prediction of Esophagitis and Z-Line from Wireless Capsule Endoscopy images using Fusion of low-level features

Since they enable immediate GI tract inspection, wireless endoscopy capsule pictures areoften used to diagnose digestive tract disorders. Scale-Invariant Feature Transform and Auto Color Corrogram are two of the design tools used to coordinate the texture, color, and shape characteristics gathered from points of interest. We evaluated the results with extensive testing involving 100 normal-z-line WCE photos and 100 esophagitis, using Na00efve Bayes, Support Vector Machine, and Random Forest. From the experimental findings, it is expected to use the new system to distinguish esophagitis and normal-z-line from WCE photos.

Multi-Scale Hybrid Network for Polyp Detection in Wireless Capsule Endoscopy and Colonoscopy Images

In the detection of small polyps in wireless capsule endoscopy images, the trade-off between speed and precision is a key step forward. We develop a hybrid network of an inception v4 architecture-based single-shot multibox detector that can detect small polyp regions in both WCE and colonoscopy frames in this paper. The biggest barriers to WCE image acquisition are medical privacy issues, which are deemed the top barriers. To meet object detection standards, we enlarged the training datasets and investigated deep transfer learning techniques. The Hyb-SSDNet framework incorporates inception blocks to eliminate the inherent limitations of the convolution algorithm's ability to incorporate contextual features and semantic data into deep networks. The feature map fusion is transmitted to the next layer by a map fusion, followed by some downsampling blocks to produce new pyramidal layers at Then. This work shows that deep learning has the ability to continue to conduct future studies in polyp detection and classification tasks.

Modified method of patency judgement using patency capsule prior to capsule endoscopy in clinical practice

This research was designed to determine the reliability of our update on the passage criteria for this PC in clinical practice. We retrospectively enrolled 326 patients who underwent PC examination before SBCE. We estimated it as u2018estimated patencyu2019 and met SBCE if X-ray could not reveal the PC in the body during the decision time. A Crohn's disease patient had a residual coating film identifying stenosis in a patient with Crohn's disease, according to one SBCE lawsuit, but one SBCE case had capsule retention as a result of inaccurate CT results. In conclusion, PCs are useful for determining gastrointestinal patency, despite CT misjudgement.

Artificial Intelligence in Colon Capsule Endoscopy—A Systematic Review

This systematic review seeks to provide an overview of the available literature on artificial intelligence for studying colonic mucosa by colon capsule endoscopy and identify the appropriate action points for its use in clinical practice. Five studies published on computed polyp or colorectal neoplasia detection, and two others published research on other aspects, five of which focused on computed bowel cleansing analysis, and two others reported on other aspects. Overall, the sensitivity of the proposed artificial intelligence models was 86. 5% for bowel cleansing and 57. 1 percent for detection of polyps and colorectal neoplasia. Conclusion: Artificial intelligence for reviewing second-generation colon capsule endoscopy images is promising. With more data, convolutional neural network algorithms can be improved and tested with more information, potentially requiring the establishment of a large multinational colon capsule endoscopy database. Also, the reliability of the optimized convolution neural network models needs to be verified in a prospective setting.
