Optical biopsy for the early diagnosis of skin cancer based on images

2019-10-25T11:26:40+02:00Categories: Deep Learning, Photonics|Tags: , , , , , , , |0 Comments

Currently, the analysis of a suspicious skin lesions is done through biopsy, a process than usually takes several weeks until the definitive diagnosis is obtained. This means high personal costs, due to the uncertainty during the wait, and high economical costs to the health system, attributable to the cost of the procedure and consequent visits to the physician. Besides, the incidence of melanoma has nearly doubled in the last 10 years in the Basque Country and is growing at 10% rate per year in Spain. The 23th of May is the World Melanoma day. Tecnalia works in collaboration with the University of the Basque Country, Ibermática and NorayBio on the development of a computer aided diagnosis tool (CAD) for the early diagnosis of melanoma and basal cell carcinoma (BCC) based on images and clinical data. Molecular data related to prognosis is also being studied, as it can help to define [...]

Hyperspectral classification of elecric and electronic waste

2019-10-25T13:19:57+02:00Categories: Photonics|Comments Off on Hyperspectral classification of elecric and electronic waste

Europe creates 6.5 million tonnes of electric and electronic waste each year and 90% ends up in landfills. Estimates show that this amount will increase to 12 million by 2015. The fractions which are a result of recycling processes cannot always be sorted by conventional visual means, as happens with lead, stainless steel or aluminium – all with great chromatic similarity. Tecnalia´s Computer Vision Group, in order to automate this process, has developed its own technology which allows the sorting of these materials based on their spectral features as well as their texture. This allows the sorting of materials which are very similar both in colour as well as shape and size. This technology overcomes the limitations of current methods which are unable to sort materials that are very similar in colour, shape and size. In order to do this, new algorithms have been developed which can distinguish these [...]

Tharmal imaging process control

2019-07-10T14:16:37+02:00Categories: Photonics, Quality Control|Comments Off on Tharmal imaging process control

Industry needs to have a strict control over the different production process areas in order to guarantee the successful manufacture of a product. The steel industry, mills and any enterprise as a whole that works with high temperature products must know and control the temperatures in each area of its process. The use of handheld pyrometers or disposable temperature probes for occasional measurements is commonplace, with its associated overrun cost. Furthermore, when an average value is needed, these captures are limited to a subset of points of the measured item, therefore generating possible sources of error and inaccuracy. Not only this, but this taking of discrete measurements throughout a process can very well run continuously in time. TECNALIA provides the possibility to design and implement automated process control systems where temperature can be a critical factor both in the production process as well as in the traceability or quality [...]

Hyperspectral image analisys

2019-10-25T13:20:02+02:00Categories: Photonics, Quality Control|Tags: , |0 Comments

Hyperspectral image analysis combines the characteristics of image processing with spectrography. A hyperspectral image contains greater information than a conventional image even in non-visible wavelengths. This can help to distinguish objects that visually seem identical or to analyse different chromatic variations. Tecnalia has developed algorithms for the classification of materials based on their hyperspectral images. This system can classify different elements based on a learning of simple samples and employing regression algorithms that allow the characterization of the chemical composition of the materials in the images. These algorithms have been used in the classification of materials in several industries, such as: recycling, slag classification, forest classification based on aerial images, the food industry or chromatography and colour characterization, to name a few.

PICCOLO project Kick-off meeting

2019-07-19T11:04:10+02:00Categories: Photonics|Tags: |0 Comments

PICCOLO (ID: 732111) project kick-off meeting, funded by the European Commission under H2020 Photonics KET topic, was celebrated in Tecnalia Headquarts located in Derio (Spain) the 18th and 19th of January. Representatives from the different project partners participated in the meeting: Karl Storz Gmbh (Germany), L4T-Light4tech (Italia), Tyndall – University College Cork (Ireland), M-Squared Lasers Limited (UK), LENS – Laboratorio Europeo di spettroscopie non lineari (Italy), CCMIJU – Fundación centro de cirugía de mínima invasión Jesús Usón (Spain), Imperial College of science technology and medicine (UK), Bioef – Fundación Vasca de innovacion e investigacion sanitarias (Spain), and the project coordinator Tecnalia (Spain) . With a duration of three years, PICCOLO has as main objective the design and development of a multimodal photonic endoscope with high sensitivity that will facilitate real time diagnosis of colon cancer via a computer aided diagnosis (CAD) system. The project has a multidisciplinary team: pre-clinicians, clinicians, photonics [...]

Fitovid Project on TV

2019-07-10T14:10:27+02:00Categories: Photonics|Tags: , , , , , , , , , |0 Comments

The Fitovid project, which main objective is the reduction of phytosanitary products in viticulture, has recently appeared on the Sustraia news magazine broadcasted on EiTB. The Computer Vision group of Tecnalia participates in the project developing a device based on photonics that allows the early detection of the mildew fungus in grape leaves before is visible to the naked eye. Two members of the group appear in the video explaining the work developed by Tecnalia in the project and next steps.

FITOVID: Computer Vision for the early detection of mildew patogens (plasmopara viticola) in grape leaves

2019-10-25T13:20:18+02:00Categories: Photonics|Tags: , , , , , , , |0 Comments

The goal of TECNALIA in the project is the development of a new portable device based on photonicsthat will allow the early detection of mildew in the grape leaves foliar tissue. The mildew is a disease caused by the Plasmopara vitícola pathogen, endemic in wet and warm climate cultivation areas. When the environmental conditions are favourable for the development of the disease, the vineyards are always treated with fungicides, although the presence of the disease is the plans in not known with certainty. Apart from the economic impact for the winery, this practice becomes a risk for the farmer, since fungicide residues remain in the soils and berries, affecting the global quality of the grape juice and wine. The 2009/108/CE directive, has as objective achieving a sustainable use of insecticides, reducing the risks and effects of insecticides in the human health and the environment and promoting the integrated management of plagues and alternative solutions, such as [...]
