Comparative Analysis between LDR and HDR Images for Automatic Fruit Recognition and Counting

Algorithm 1

Fruits detection and counting algorithm pseudocode.

Load image

Convert RGB image to HSV image: rgb2hsv

Define: hueThresholdLow: Hue component lower threshold

hueThresholdHigh: Hue component higher threshold

smallAcceptArea: Smallest acceptable area

Apply the hue thresholds to the loaded image

Filter out objects smaller than smallAcceptArea

Define: radmin: minimum radius value

radmax: maximum radius value

sensitivity: factor for circular Hough transform accumulator array

Funtion to detect circles between radmin and radmax: imfindcircles(image, [radmin radmax], sensitivity)
