How to count objects in an image?

Hello,
I want to count the number of flowers in an image classified by its color and shape,
the flowers are sometimes overlapped, and there are only 3 (or 4 types but color would be specified):
1- Jasmin: white
2- Rose: red
3- Tulip: Violet
I need help to code this in matlab please

The approprite approach based on the type of input images, though you can follow the following (General Case)

Steps:

1. Do the segmentation
2. Separate all Flowers using Morphological Operation
3. Mask the original Image (Only ROIs are there)
4. Use color detection to counts the number of flowers (Approx Area can be use for confirmation)
