1. Introduction The analysis of natural microscopic images is the basis of many technological developments in fields such as medicine or biology [ 1, 2, 3 ]. The automatic detection of objects in images captured with an automated microscope is a challenge for many types of natural samples due to the variability of the environment.

A ctual pollen is merely the best-known subject of study, and the most spectacular. Under a microscope, the individual grains of pollen from different species can look like soccer balls, sponges, padded cushions, coffee beans, or burr balls from the sweetgum tree.

It's worthwhile viewing the washed grains (still in a little alcohol) under a stereo microscope (ca 40X or greater for larger pollen types) as the 50% glycerine is added; the hydration and swelling of the grains is interesting to watch.

Pollen grain recognition is commonly performed by visual inspection by a trained person. An alternative method for visual inspection is automated pollen analysis based on the image analysis technique. Image analysis transfers visual information to mathematical descriptions.

This method requires the subsequent counting of the pollen grains under optical microscopy, the most common and economic system to analyze samples, according to a protocol.. Obviously, when moving the position of the sample in the microscope, the pollen grain would appear complete in a new sample in the X or Y direction, and then, it would.

Analysis of pollen material obtained from the Hirst-type apparatus, which is a tedious and labor-intensive process, is usually performed by hand under a microscope by specialists in palynology. This research evaluated the automatic analysis of pollen material performed based on digital microscopic photos.

The largest pollen grains are around 200 µm in diameter, and the smallest are less than 10 µm, so you need a microscope to study them. At 100× you can see the grains, at 400× you can start to see details, and at 1000-1500× you can see enough details to make a good drawing.

Pollen grains are produced by meiosis of microspore mother cells that are located along the inner edge of the anther sacs. [In this figure] The anatomy of a flower. The stamen is a male part of the flower. The stamen contains filament and anther where the pollens are produced. The stigma is a female part of the flower. The structure of pollen
