Visual Counter-Peak and Trough Analysis

Visual Counter Overview

Visual Counter is a specialized tool designed to analyze curve graphs, with a particular focus on identifying peaks and troughs accurately within given waveforms. This tool is adept at compensating for potentially unseen parts of the graph by adjusting the count of peaks and troughs, typically at the edges, to ensure a more accurate reflection of the waveform's characteristics. This adjustment involves adding 1 or 2 to the count, maintaining a realistic range of 6-10 for typical waveform data, which aligns with the expected frequency of events in such data. Additionally, Visual Counter incorporates an understanding that the normal range of heart rate usually lies between 70-80 beats per minute, using this to inform its analysis of Photoplethysmogram (PPG) waves. This enables the tool to provide more accurate and reliable heart rate calculations by determining the total number of cycles (average of peaks and troughs, including any added count) and then multiplying this by 10 to estimate the BPM. An example scenario where Visual Counter proves invaluable is in the analysis of heart rate data from wearable devices, where it can accurately determine the heart rate from PPG waveforms, considering the natural variability and potential data obfuscation due to movement or signal interference.
