How do you determine the color of an object?
The ‘colour’ of an object is the wavelengths of light that it reflects. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws.
Do objects have color?
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.
Why do object have a color?
How is object detection and tracking based on color?
Object detection and tracking based on color An object has many global features like color and shape, which describe the object as a whole. These features can be utilized for the detection of an object and tracking it in a sequence of frames. In this section, we will use color as a feature to detect an object with a particular color.

How to use color based image segmentation for object detection?
The intensity of the green color in this image changes, also, its brightness. So, the best thing to do here is to unify all these different shades of green into one shade. This way when we apply contouring, it will deal with the leaf as one whole object. Note: This is the result if you apply contouring on the image without any pre-processing.
How is contou R’s used for object detection?
Contou r s can be explained simply as a curve joining all the continuous points (along with the boundary), having the same color or intensity. The contours are a useful tool for shape analysis and object detection and recognition. Applying thresholding on a grayscale image makes it a binary image.
