Discover in under a minute cancer cells is closer thanks to an advanced artificial vision developed in Ecuador the Venezuelan scientist Oscar Chang.
The engineer, who is in the Andean country as part of the Prometheus Project, develops a program of advanced computer vision, computer aided, for use specifically on tests gentle scraping of the cervix, better known as Pap order to identify malignant cells.
“A technician will take about 20 minutes analyzing Pap sample, with this program we can do it in a minute Another advantage is that it strains the eyes of the technician, so that samples do not accumulate and faster diagnoses are made, which helps treat. time cancer if the cells are discovered, “Chang says.
the system is a software developed by Venezuela, which works through a network of artificial neurons. To train networks Pap real plates taken from Ecuadorian patients were used.
The technique for networks to learn to identify what they want is known as Deep learning . This is a learning system for networks that use different layers to make these readings. layers are handled and this specific system requires at least six layers. After placing the information in the program, it will be responsible for scanning the sample and the display will see the result: an image of the sample on which to found a cancer cell, the system enclosed in a small circle, which identifies it as evil.
the project is 85% advanced and the researcher expected by April next year is finished.
“the idea is to build a prototype and give it to a health center. the costs for these analyzes would fall considerably and patients would benefit, “he explains.
The engineer, also expert in robotics and mechatronics, ensures that there only to find cancer cells serves its software, but also for other investigations, which are ongoing.
says Oscar Chang that currently five students perform different theses from machine vision system. In one stand use to diagnose Chagas disease with just a drop of blood; another, records the number of people using the public bus system Ecuador, and the third is used to classify strawberries.
