“…The samples with a thickness of 6 mm were randomly sectioned along the longitudinal direction of the sample, and the micro-characteristics of the cross-section of the sample were observed under a highpower optical microscope, as shown in Figure 1 to study the micro-characteristics of unidirectional laminates with different thicknesses. Image analysis [6][7][8] shows that the volume fraction of fiber in samples with different thicknesses is about 53%, and the diameter of the fiber is 10 m μ . Through quantitative analysis of pore geometry parameters, the parameters related to irregular pores of samples with different thicknesses, such as porosity, area, and roundness factor, can be obtained.…”

Through section analysis and optical microscope observation of thick-section composite materials, it is found that there are significant differences in pore micro-characteristics of samples with different thicknesses. It is pointed out that the difference in pore micro-characteristics in the composite matrix is one of the reasons for the change in the interlaminar shear strength of composite materials. In this paper, irregular pore profiles are obtained through image processing, and the parameters to quantitatively characterize the microscopic characteristics are proposed. A randomly generated three-dimensional representative volume element (RVE) model including fiber, matrix, fiber/matrix interface, and pores. The effect of irregular pores with different sizes and distributions on the interlaminar shear strength of composite materials is given. The RVE numerical analysis results show that the interface failure between the fiber and the matrix near the pore causes damage. At the same porosity, the shear strength decreases with the increase of the maximum pore size. At the same time, the porosity concentration also has a significant effect on the interlaminar shear strength of thick section composite. The numerical results verify that the influence of pores on the interlaminar shear properties of thick-section composites is related to the microscopic characteristic parameters of pores.

“…There are many methods of edge detection on the image, some of which are widely used are Canny, Sobel and Prewitt [2] [4] [7]. Each detector has its own advantages and disadvantages, so the edge area produced by each method is different.…”

“…In smooth areas, changes in pixel values will be more easily detected by human vision [2] [4]. Getting the edge area can be done with an edge detector like Canny, Sobel, and Prewitt [2] [4] [7]. The use of edge detection can also improve the security aspects of messages because the way embedding is not done in sequence [11].…”

This research proposes a method to enhance the payload message by embedding messages on the dilated edge areas by the Least Significant Bit (LSB) method. To add security aspects to messages, messages are not embedded directly on the LSB but encrypted with XOR operations with Most Significant Bit (MSB). The experimental results of the test in this study showed that the dilation process to some extent can increase the payload of 18.65% and the average bpp is 1.42 while maintaining the imperceptibilty quality of stego image with an average PSNR value of about 47 dB, SSIM is 0.9977 and MSE is 1.13.
