Bio

Itzel is currently studying artificial intelligence as an undergraduate at the Panamerican University in Aguascalientes, Mexico. She spends her time participating in programming contests, and she and her team are doing their best to get to the world finals next year. Last summer she worked as a software engineer intern at Facebook. She had an exciting summer in the Wolfram Summer School.

Project: Figure Out the Value of a Resistor from an Image

Goal of the project:

To output the value of a resistor given a photo of it. The photos are intended to be taken on a white background, like a white sheet of paper, with a cellphone camera.

Summary of work:

Many samples are used in a classifier, leaving, as a result, a logistic regression. All training and test samples were rotated and cropped automatically. The resistor position is found using morphological components, then the picture is cropped and rotated, leaving the resistor to cover the majority of the picture. Using the classifier, we obtain the final result.

Results and future work:

The project is limited to a small set of resistors for which it can calculate the value. The next step is to either crop the color bands of the resistor and use machine learning in a similar way to determine the color of each of the bands of the resistor or improve the current machine learning methods to increase the extent of the project.
