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.

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.

Reconstruction of rough surfaces with shape from focus
Reconstruction of the 3D shape of a surface viewed under the microscope is particularly challenging, owing to the irregular shapes that a surface can take. Irregular surfaces having many sharp bends and peaks have a high frequency texture pattern which needs to be smoothed out through a low-pass filter. The shape-from-focus method provides the framework to do just that, thanks to its ability to stably reconstruct a high frequency surface, as seen in electron microscopy.

Date sorting
RSIP Vision has successfully worked in number of dates grading (or dates sorting) projects for our clients. Our automatic fruit recognition system is able to identify with high speed and accuracy all meaningful product features such as size, weight, defect, quality, color, texture, ripeness and others, offering key benefits to our clients: namely, fast and high-volume classification, savings in labor costs, consistent quality and reduced time-to-market.
