Bio-composite Material Characterization Based on Field Emission Scanning Electron Microscopy Images

Measuring the texture properties of the sample surface is an important matter for bio composite materials. In this research, the samples were prepared from egg shells and palm fronds, and a set of pictures were taken in the Field Emission Scanning Electron Microscopy (FESEM) of many samples before and after hydrochloric acid immersion. Then, the image processing and analysis phase begins by taking images of different sizes and measuring the texture properties of the images. The statistical measurement results were performed on the samples to specify their effect on the acid solution. Many factors were applied, including; contrast, dissimilarity, homogeneity, angular second moment, maximum probability, entropy, energy, mean, variance, and correlation. After studying and comparing the samples' results and examining the acid effect on them, it was found that the two samples are resistant to acid immersion; the palm frond sample is more resistant to acid immersion than the eggshell sample. The results are quite acceptable compared with the previous studies.
