  • Classifying Healthy and Defective Fruits with a Multi-Input Architecture and CNN Models
    Luis Chuquimarca, Boris Vintimilla, and Sergio Velastin

    IEEE
    This study presents an investigation into the utilization of a Multi-Input architecture for the classification of fruits (apples and mangoes) into healthy and defective states, employing both RGB and silhouette images. The primary aim is to enhance the accuracy of CNN models. The methodology encompasses image acquisition, preprocessing of datasets, training, and evaluation of two CNN models: MobileNetV2 and VGG16. Results reveal that the inclusion of silhouette images alongside the MultiInput architecture yields models with superior performance compared to using only RGB images for fruit classification, whether healthy or defective. Specifically, optimal results were achieved using the MobileNetV2 model, achieving 100% accuracy. This finding suggests the efficacy of this combined methodology in improving the precise classification of healthy or defective fruits, which could have significant implications for applications related to external quality inspection of fruits.

  • Enhancing Apple’s Defect Classification: Insights from Visible Spectrum and Narrow Spectral Band Imaging
    Omar Coello, Moisés Coronel, Darío Carpio, Boris Vintimilla, and Luis Chuquimarca

    IEEE
    This study addresses the classification of defects in apples as a crucial measure to mitigate economic losses and optimize the food supply chain. An innovative approach is employed that integrates images from the visible spectrum and 660 nm spectral wavelength to enhance accuracy and efficiency in defect classification. The methodology is based on the use of Single-Input and Multi-Inputs convolutional neural networks (CNNs) to validate the proposed strategies. Steps include image acquisition and preprocessing, classification model training, and performance evaluation. Results demonstrate that defect classification using the 660 nm spectral wavelength reveals details not visible in the entire visible spectrum. It is seen that the use of the appropriate spectral range in the classification process is slightly superior to the entire visible spectrum. The MobileNetV1 model achieves an accuracy of 98.80% on the validation dataset versus the 98.26% achieved using the entire visible spectrum. Conclusions highlight the potential to enhance the method by capturing images with specific spectral ranges using filters, enabling more effective network training for classification task. These improvements could further enhance the system’s capability to identify and classify defects in apples.

  • Automated Quality Control System for Canned Tuna Production using Artificial Vision
    Sendey Vera Gonza’Lez, Luis Chuquimarca Jimenez, Wilson Galdea Gonzalez Given, Bremnen Véliz Noboa, and Carlos Saldaña Enderica

    IEEE
    This work presents the implementation of an automated control system for detecting and classifying faults in tuna metal cans using artificial vision. The system utilizes a conveyor belt and a camera for visual recognition triggered by a photoelectric sensor. A robotic arm classifies the metal cans according to their condition. Industry 4.0 integration is achieved through an IoT system using Mosquitto, Node-RED, InfluxDB, and Grafana. The YOLOv5 model is employed to detect faults in the metal can lids and the positioning of the easy-open ring. Training with GPU on Google Colab enables OCR text detection on the labels. The results indicate efficient real-time problem identification, optimization of resources, and delivery of quality products. At the same time, the vision system contributes to autonomy in quality control tasks, freeing operators to perform other functions within the company.

    Alfonso Gunsha-Morales, Luis Enrique Chuquimarca Jimenez, Pedro Pardo, and David Herrera

    IEEE
    This project centers around creating a prototype mouse utilizing the Arduino platform, aimed at enhancing computer accessibility for individuals lacking upper limb mobility. The prototype comprises a microcontroller responsible for processing signals from the MPU-6050 sensor, used as a reference for cursor position, and foot-operated buttons for right and left-click functions. Its design enables cursor control through head movements, providing users with an easy and intuitive way to interact with the computer's graphical interface. Feasibility testing was conducted through experimental trials, resulting in ideal accuracy and precision. These trials indicate that the device is viable for use in individuals without upper limbs.

  • Implementation of an Electronic Monitoring Device Using Computer Vision for Non-Invasive Respiratory Rate Measurement
    David Sánchez, Luis Chuquimarca, Óscar Gómez, Manuel Montaño, and Mario Salcedo

    IEEE
    An electronic monitoring circuit has been developed to detect a person's respiratory rate without requiring medical professionals or physical contact, thereby improving patient comfort. The Eulerian Video Magnification method and the Optical Flow technique were applied in computer vision to obtain, quantify and analyze respiratory movements using videos in an efficient manner that standard sensors might misread. The circuit can perform constant monitoring at low cost using a Raspberry pi camera OV5647 which has an intuitive interface to be used for the analysis. Comparative tests were conducted between the proposed device and a traditional thermistor-based nasal sensor. The findings showed that the non-invasive device achieved a high precision rate, closely matching the accuracy of the traditional method, with a margin of error below 1.5% in well-lit environments. The results indicate that computer vision can be implemented to develop efficient, low-cost medical monitoring solutions for clinical and homecare environments.

  • KALMAN FILTER APPLIED TO A DIFFERENTIAL ROBOT
    Sendey Vera Gonzalez Facsistel, Luis Chuquimarca Jiménez Facsistel, and Douglas Plaza Fiec

    IEEE
    This document presents the localization problem and the trajectory that a robot must follow. It focuses on applying the Kalman filter to achieve localization and trajectory estimation in an autonomous mobile differential robot. The experimental data was obtained through tests conducted by using two incremental encoders that are part of the instrumentation of the differential robot. Data transmission is carried out from a PC, where control is performed using Matlab/Simulink software. The results are presented in graphs showing the robot's trajectory using PI control and the Kalman filter estimator in a real scenario.

    American Society for Microbiology
    Structure of RbdA, a Regulator of Biofilm Dispersal of Pseudomonas aeruginosa Understanding how proteins containing tandem GGDEF-EAL domains control c-diGMP concentration is crucial for deciphering the mechanism of c-di-GMP signaling. Liu et al. (e00515-17) determined the crystal structure of the PAS-GGDEF-EAL portion of RbdA, a bifunctional protein that regulates dispersal of Pseudomonas aeruginosa biofilms. Together with biochemical data, the crystal structure points towards a highly flexible protein that undergoes dramatic structural rearrangements to control the activity of its GGDEF and EAL domains for c-di-GMP synthesis and degradation. This work sets the stage for a better understanding of the highly dynamic regulatory mechanism that underpins the biological functions of GGDEF-EAL-containing proteins.

    Luis Chuquimarca, Dahyana Roca, Washington Torres, Luis Amaya, Jaime Orozco, and David Sanchez

    IEEE
    The system was developed using a mobile electronic device for monitoring and warnings the heart problems when the heart rate is outside the nominal range, which ranges is from 60 to 100 beats per minute. The system has been developed to save and monitor in real time changes of the cardiac pulsations through a sensor connected to a control system. The connection of the communication module was made using Arduino GSM/GPRS/GPS. This platform allows to locate the user using the GPS network and connects with GSM / GPRS technology to sent text messages to the contact number configured in the device when warnings of heart problems are issued. Moreover, it connects to the internet to store data in the cloud.
