According to reports ImmenaAnemia occurs in about 25% of the world’s population. Fatigue, dizziness, headache, shortness of breath, and difficulty concentrating are common symptoms of low-grade hemoglobin, but severe anemia following malnutrition, parasitic infections, or underlying conditions may occur. Vulnerable groups are an important cause of death and میر Are.
Using a smartphone camera to take pictures of the lower eyelid can detect anemia with 72% accuracy. It is true that anemia can be detected by testing blood and calculating the amount of hemoglobin in the blood, but in some rural areas it is difficult due to lack of access to medical centers. This indicates the need for the availability of inexpensive, non-invasive tools and equipment.
Researchers detect anemia in two phases using a smartphone camera. In the first phase, they took pictures of the lower eyelids of 142 patients. The reason why the lower eyelid was chosen by the researchers is that it is easy to photograph; There is no other barrier between the blood vessels and the surface of the conjunctiva; The distance between the surface and the blood vessels is very small and temperature and other environmental factors do not affect the blood flow in this area.
In the first phase, the researchers are able to create an algorithm that maximizes the color sharpness and the predictive model of comparing the skin and whiteness of the eye with the hemoglobin level by magnifying the small points of each image.
In the second phase, they tested the algorithm on smart images of 202 different patients. The findings show that this model is 72.6% accurate in predicting anemia. This method is higher in the diagnosis of severe anemias that require blood transfusions and reaches 86 and 94.4%.
Use a smartphone because of anemia screening, avoid the need for blood Giri And it saves a lot of time. Smartphone camera images capture data directly from the camera sensor without the usual processing and compression created in the format های Usually creates a photo.
