1. A system to analyze heart data, the system comprising:
a memory configured to store echocardiographic strain image data; and
a processor operatively coupled to the memory and configured to:
segment the echocardiographic strain image data, wherein segmentation of the echocardiographic strain image data extracts a scale and graph data from the echocardiographic strain image data, wherein the processor is configured to convert the graph data into a two-dimensional array of hue saturation values;
analyze the segmented echocardiograph strain image data to generate a point cluster of pixels;
stitch together points in the point cluster to generate a continuous curve that represents at least a portion of the echocardiographic strain image data; and
analyze the continuous curve to identify a heart condition.
