The paper is devoted to the development of a computational technique for assessing the performance of tissue regeneration in an experiment using mesh nickel-titanium implants with shape memory. Observational data obtained from electron microscopy and classical histological examination are processed and analyzed by the use of proprietary algorithms and their modifications. This can significantly facilitate the procedure of data analysis and increase the accuracy of the estimates by 5–10%. As a computational method for examining the dynamics of the studied process and determining the internal geometrical characteristics of empirical images of objects concerned, the suggested technique includes algorithms of shearlet transform, wavelet transform and construction of elastic maps for efficient visualization of spatial data. The significant part of the recommended method is the computing means of visual data preprocessing for increasing the brightness and contrast of the examined images based on the Retinex technology. This part has a significant impact on the quality of applying the tools of the computer-based evaluation presented in this work.

Recently, steganography and steganalysis have been received an increasing attention due the nature of our modern societies which depends on exchanging information on a large scale. Steganography is the art of communication through sharing secret messages by embedding them into useless cover messages. The cover message can be an image, audio, or video file. On the other side, the steganalysis techniques are concerned with discovering the existence of steganography. This paper presents a specific image steganalysis technique with main objective is to detect the existence of steganography made by the least significant bit (LSB) technique in a certain image. The proposed approach extracts the gray level co-occurrence matrix (GLCM) as salient features which capable to distinguish a stego image from a non-stego one using a Back-Propagation (BP) classifier at the classification phase. Experimental results on standard datasets that consists of 297 images are encouraging. The proposed method is robust and high accuracy level has been achieved.
