How do you find the HSV range of an object?

To find the HSV values of a color, we can use color space conversion from BGR to HSV. First we define the color value in BGR format as numpy. ndarray and then convert it to HSV space. We can also find the lower and upper limits of HSV value as [H-10, 100, 100] and [H+10, 255, 255] respectively.

How do you define range of color in HSV?

For HSV, Hue range is [0,179], Saturation range is [0,255] and Value range is [0,255]. Different softwares use different scales. So if you are comparing OpenCV values with them, you need to normalize these ranges.

How do you read HSV values?

0.80 - 0.99: Equivocal-Repeat in 10-14 days may be helpful. Greater than 0.99: Positive - May indicate a current or previous HSV infection. 0.90 - 1.09 IV: Equivocal - Repeat testing in 10-14 days may be helpful. Greater than 1.09: Positive - May indicate a current or recent infection.

What is the range of saturation values in HSV color space?

HSV Color Space

As saturation varies from 0 to 1.0, the corresponding colors (hues) vary from unsaturated (shades of gray) to fully saturated (no white component). As value, or brightness, varies from 0 to 1.0, the corresponding colors become increasingly brighter.
