Detection and quantification of bone cancer

Metastatic bone malignancies arise following prostate cancer (80% of cases, with 3% five-year survival rate), breast cancer (with no cure) or lung cancers (with 11% two-year survival rate). Bone metastases affect more than 400,000 people annually in the United States with frequent occurrences among patients undergoing irradiation and secondary effect to other treatments. Detection of skeletal metastases has a major impact on devising treatment strategies and prognosis. The solution offered by RSIP Vision produces 3D surfaces of bones and other skeletal-related structures to detect and quantify primary and metastatic bone cancer.

Point and surface registration in orthopedics

Point and surface registration enable computer vision and image processing to improve surgical orthopedy practices and affect surgery outcome recovery. Bringing point and surface registration in the field of orthopedics, computer vision and image processing hold the potential to improve surgical practices and affect surgery outcome to favor the benefit of patients and fast recovery. Measurement accuracy (within less than 1 mm) is a strict constraint to computer-vision-based algorithms.

Automatic human action recognition in videos

When a video uploader disregards adding tags and categories, online video hosting platforms encounter what is called the new item problem. This can be solved by utilizing visual analysis of videos and images: first, by filtering videos into recognizable objects and combining human action segmentation and recognition; later, by training Multiclass Support Vector Machines to assign labels to detected actions in the temporal domain of videos.

Automatic semantic tagging of images

Sites containing huge amounts of content must necessarily recommend only a narrow and relevant list to users. Recommender systems can be seen as tool to automatically generate personalized search preferences, with the purpose of keeping the balance between monetized targeted suggestions and satisfactory user experience. Automatic semantic tagging helps them do just this.

Automatic video categorization of new item

Online video hosting platforms utilize a variety of methods for content discovery. Recommender systems allow users to face the huge amount of information offered to their view: recommendation algorithms analyze the video and automatically suggest a confined set of adequate tags to the uploader. Alternatively, the system learns to automatically assign tags to videos without any user intervention.

Visual Search and Video Recommendation

Here is a simple explanation of how a Recommender System work. Take YouTube as an example: a huge quantity of videos needs to be processed, classified, tagged and ranked by users or by an automatic algorithm, before it can be used by the Recommender system. Learn how users are classified by filtering (either collaborative, content-based or hybrid) and videos are ranked by similarity.

Vehicle Localization with Lane Tracking

More than 1 million people killed and 50 million injured on the roads every year make driving safety a subject of the highest importance. ADAS technologies are at the forefront of this fight: a further proof of that is our car detection and localization solution enabling to detect a danger, create an alert, avoiding the obstacle or – in the worst case – minimizing damage. This system based on machine learning follows the highest quality standards and can save lives on the road.

Pedestrian Detection with Machine Learning

One of the most challenging tasks of ADAS operating in urban or rural environment is the detection of pedestrians. When human behavior can sometimes be unpredictable, ADAS systems can be programmed to track pedestrians and predict with high levels of accuracy their orientation and intentions: human lives are at stake and our software is key to save them. RSIP Vision‘s algorithms do not save lives only in medical applications, but also in automotive safety systems!

Fabric Inspection with Texture Analysis

Vision-based production inspection systems using camera-based scanning are now quite common in in-line production lines such as in steel, leather and fabrics manufacturing. Inspection is a crucial process since it can reduce process and enhance product quality. We recommend here a texture analysis for defect and novelty detection in fabrics and non-structured surfaces. Our fabric inspection algorithms are developed to detect deviations from local pattern and texture, anomalies and defects.

3D inspection and crack detection

Industrial production is prone to surface defects and it often needs to be inspected prior to shipment, when still in a semi-finished status. Cracks being very frequent in many types of material, vision-based crack inspection and detection is cost effective and offers high reproducibility and reliability. Here is a contact-free procedure using laser scanning, which can be placed in-line for continuous inspection during production.

Road signs detection with machine learning

Frequent variations of speed limits (mainly due to roadwork and other maintenance), offer ADAS technology a chance to help drivers respect traffic laws and security. The traffic signs detection software developed by RSIP Vision detects a road sign at distance and verifies via machine learning if it is a speed limit sign and what that limit is. These detection and classification processes being based on machine learning, our application is able to do things that regular “engineered” software cannot do.

Flat Panel Display Inspection

This project compares the performance of a new inspection procedure of Flat Panel Displays (FPD) with the results obtained using a previously existing process. The goal was to demonstrate the correct detection and defect position reported by the new technology. This was done by putting in place a system in charge of image acquisition software and control which drives the captured frames to a sophisticated algorithmical registration analysis system developed by RSIP Vision.

Wafer defect detection by feature matching

Detection of microscopic defect in wafers and printed circuit boards is a standard procedure in the manufacturing process. The time consuming human inspection has been replaced in nearly all production lines with an automatic in-line camera-based examination, which can be very effective usingcomputer vision and image processing technologies to detect any anomalies. Via algorithms of feature extraction and matching, RSIP Vision is able to track defects leading to dramatically improvements in reliability and usability.

Detect barcode or QR with camera-based scanners

Barcode Detection in complex environments

Automatically localizing and reading barcodes captured by a smartphone-based cameras have great value for industrial and personal applications but create new technical challenges: quality of the image, motion blurs, unpredictable distance to barcode, non-uniform orientation and unknown location of the barcode itself. Image processing and computer vision algorithms can solve these issues: ask RSIP Vision how we do it.

Real time OCR in natural scenes

With the advancement in technology, the demand for OCR in natural environment is growing, even though outdoor conditions are far from being optimal for machine vision applications: occlusion of written text, text orientation, font style, blurring due to camera motion, and lighting conditions can prove themselves significant challenges in the task of performing real time OCR. Great progress has recently been made in the recognition of characters partially occluded and under heavy noise. RSIP Vision tells you how.

Live cells tracking

Manual cell inspection is limited to tracking a relatively small number of cells in short periods of time and it is prone to human errors. On the other hand, computer vision algorithms can be used to perform fast scanning, segmentation and tracking of large cell populations over long periods of time. Taking advantage of our experience in segmentation, microscopy and machine learning, this procedure helps saving both labor and time, hence enabling more timely diagnostic and therapy.

Chromosome classification

Chromosomes are organized structures containing most of living organisms’ DNA. Though important to detect major troubles to an individual’s growth, development and body functioning, the test which identifies and evaluates size, shape and number of chromosomes in the body cells needs human expertise, which is currently very rare. RSIP Vision decided to use convolutional neural networks to perform this chromosomes automated classification with machine learning.
