DETECCIÓN DE AUTOMÓVILES EN UN ESTACIONAMIENTO UTILIZANDO RED ICM Y GLCM (CAR DETECTION IN A PARKING LOT USING ICM AND GLCM)

Resumen Los sistemas de visión por computadora cada vez están siendo empleados con mayor frecuencia para desempeñar tareas en ambientes urbanos, siendo la detección de automóviles uno de los principales objetivos, ya que permiten ser utilizados para diferentes aplicaciones, por ejemplo, para identificar tráfico vehicular o bien identificar lugares disponibles en estacionamientos, entre otras aplicaciones; algunos inconvenientes que se presentan en la detección de automóviles, es la variedad de tonalidades de color que pueden presentar los autos, así como los efectos de oclusión y cambios de posición de la cámara de captura. En este trabajo se presenta un método de detección de automóviles en un estacionamiento basado en el uso de red ICM para segmentación y la GLCM en la extracción de características de textura para el reconocimiento de los automóviles. Se realizaron pruebas con 57 imágenes obteniendo una efectividad del 90% en la detección de los automóviles. Palabras Clave: aprendizaje, detección, reconocimiento, segmentación, textura. Abstract Computer vision systems have been increasing the use for urban environments tasks, where car detection is one of the principal objectives, because it lets been using for different applications like, vehicular traffic detection, or available parking lots at parking lots, and others more. Some inconvenient presented during car detection are, the color variety that cars can present, as well as occlusion effects, and camera position changes. This work presents a method for car detection in a parking lot based in the use of ICM for segmentation and GLCM on texture features extraction used for car recognition. Test were performed using 57 images, reaching 90% effectivity on the car detection. Keywords: detection, learning, recognition, segmentation, texture

Reduction of cardiac imaging tests during the COVID-19 pandemic: The case of Italy. Findings from the IAEA Non-invasive Cardiology Protocol Survey on COVID-19 (INCAPS COVID)

Background: In early 2020, COVID-19 massively hit Italy, earlier and harder than any other European country. This caused a series of strict containment measures, aimed at blocking the spread of the pandemic. Healthcare delivery was also affected when resources were diverted towards care of COVID-19 patients, including intensive care wards. Aim of the study: The aim is assessing the impact of COVID-19 on cardiac imaging in Italy, compare to the Rest of Europe (RoE) and the World (RoW). Methods: A global survey was conducted in May–June 2020 worldwide, through a questionnaire distributed online. The survey covered three periods: March and April 2020, and March 2019. Data from 52 Italian centres, a subset of the 909 participating centres from 108 countries, were analyzed. Results: In Italy, volumes decreased by 67% in March 2020, compared to March 2019, as opposed to a significantly lower decrease (p < 0.001) in RoE and RoW (41% and 40%, respectively). A further decrease from March 2020 to April 2020 summed up to 76% for the North, 77% for the Centre and 86% for the South. When compared to the RoE and RoW, this further decrease from March 2020 to April 2020 in Italy was significantly less (p = 0.005), most likely reflecting the earlier effects of the containment measures in Italy, taken earlier than anywhere else in the West. Conclusions: The COVID-19 pandemic massively hit Italy and caused a disruption of healthcare services, including cardiac imaging studies. This raises concern about the medium- and long-term consequences for the high number of patients who were denied timely diagnoses and the subsequent lifesaving therapies and procedures

Impact of COVID-19 on Diagnostic Cardiac Procedural Volume in Oceania: The IAEA Non-Invasive Cardiology Protocol Survey on COVID-19 (INCAPS COVID)

Objectives: The INCAPS COVID Oceania study aimed to assess the impact caused by the COVID-19 pandemic on cardiac procedure volume provided in the Oceania region. Methods: A retrospective survey was performed comparing procedure volumes within March 2019 (pre-COVID-19) with April 2020 (during first wave of COVID-19 pandemic). Sixty-three (63) health care facilities within Oceania that perform cardiac diagnostic procedures were surveyed, including a mixture of metropolitan and regional, hospital and outpatient, public and private sites, and 846 facilities outside of Oceania. The percentage change in procedure volume was measured between March 2019 and April 2020, compared by test type and by facility. Results: In Oceania, the total cardiac diagnostic procedure volume was reduced by 52.2% from March 2019 to April 2020, compared to a reduction of 75.9% seen in the rest of the world (p<0.001). Within Oceania sites, this reduction varied significantly between procedure types, but not between types of health care facility. All procedure types (other than stress cardiac magnetic resonance [CMR] and positron emission tomography [PET]) saw significant reductions in volume over this time period (p<0.001). In Oceania, transthoracic echocardiography (TTE) decreased by 51.6%, transoesophageal echocardiography (TOE) by 74.0%, and stress tests by 65% overall, which was more pronounced for stress electrocardiograph (ECG) (81.8%) and stress echocardiography (76.7%) compared to stress single-photon emission computerised tomography (SPECT) (44.3%). Invasive coronary angiography decreased by 36.7% in Oceania. Conclusion: A significant reduction in cardiac diagnostic procedure volume was seen across all facility types in Oceania and was likely a function of recommendations from cardiac societies and directives from government to minimise spread of COVID-19 amongst patients and staff. Longer term evaluation is important to assess for negative patient outcomes which may relate to deferral of usual models of care within cardiology
