Abstract

The use of digital images is increasing because of the advantages possessed by digital images, the lighting quality in digital images that are too dark or too bright. Where this noise is usually obtained from the image digitization process. Noise in digital image processing is a disturbance caused by deviating digital data received by the recipient of image data. The elimination of noise in the image is one of the most important parts in image processing. In the process, the images is on. The input is converted into 3x3 matrix then the process uses the contrast streching method for fix the noise from the image. In this study using the Contrast Stretching method and the Convolution method so that the objects and backgrounds in an image can be recognized more clearly

Abstract

During the current pandemic, keep a sound safe framework. also, obviously to know it all we need to actually take a look at it. The heart is one of the fundamental organs possessed by people whose capacity is to siphon blood all through the body. Pulse Beats Per Minute (BPM) is a boundary to decide the state of the heart and the way of deciding the state of the heart is to know the recurrence of the heartbeat. What's more, with the assistance of a temperature sensor, it will be more useful to know the state of our body. This body condition observing apparatus is planned dependent on NodeMCU ESP8266, temperature sensors DS18B20 and MAX30102 to recognize pulse. This examination was led to make it simpler for us people to control the soundness of our bodies at whatever point and any place we need. The pulse and internal heat level information from the observing device will be shown on the OLED LCD and the outcomes from the sensors will be shown on the OLED LCD and furthermore a sound notice that contains data regarding if your body is in acceptable condition dependent on the consequences of the two sensors.
