matlab cvst - boundary error of image processing Index exceeds matrix dimensions. error

Question

The name of the fruit captured by the camera. Dimensional analysis and color analysis were done. I can't get results due to error. I run a code and "Index exceeds matrix dimensions" appears as an error but I don't understand why.

Index exceeds matrix dimensions.

this is a carrot so must be in the following range and the printout should write carrots

text(centroid(1), centroid(2),'Havu?');



elseif (metric <= 0.6955) && (metric >= 0.6920) && 'Color', [1 0 0], ... // K?rm?z? color
