You need to have a set measurement to begin any additional measurements of an image.
Treat the sole as a rectangle. measure length and width. If there is a curve, estimate center of curvature. measure radius. measure length of curve in arc lengths. Determine number of radians. use formula for cylinder, replacing 2 (pi) with number of radians. Subtract length of shoe by the length of curve in the sole. Calculate area
You can measure the length of a curved line by using a flexible measuring tape following the curve or by breaking it down into smaller straight segments and adding them up. Another option is to use a formula that calculates the arc length of a curve based on its equation and limits.
To measure the length of a curved line using a thread and divider, first, place the thread along the curve, ensuring it follows the curvature closely without any slack. Once the thread is laid out along the entire length of the curve, mark the point where it meets the starting point. Then, remove the thread and use a ruler to measure the length of the section of the thread that corresponds to the curve. Alternatively, you can use the divider to mark intervals along the thread and then measure those intervals to get a more accurate length.
A Koch curve has INFINITE length.
they are used to determine the level of detail represented by the image. if the image has low level of detail, the curve will be more curved. If the image has high level of detail, the curve tends to be vertical.
They are determined by multiplying the horizontal pixels of an image by the vertical ones.

To find the focal length of a lens, you can use the lens formula: 1/f 1/do 1/di, where f is the focal length, do is the object distance, and di is the image distance. Measure the object and image distances from the lens, then plug the values into the formula to calculate the focal length.

You can measure a curved line on a map by using a string or measuring tape to match the curve and then measuring the length against a ruler or a map scale. Alternatively, you can break down the curve into smaller straight line segments and then add up their lengths to get an estimate.
