Building crack monitoring is of great value to the judgment of building safety. In this study, the digital image processing technology was studied and applied to the monitoring of building cracks. Crack images were collected by CCD camera, and then operations such as graying, correction, denoising and segmentation were carried out to obtain clear crack images. The obtained images were processed morphologically to further improve the quality. Finally, the width and length of cracks were calculated. In the case analysis, the results of 15 cracks measured by a microscope were taken as the standards and compared with the calculated results. The results showed that the results calculated in this study and the manual measurement results differed little, and the average errors of the width and length were 0.021 mm and 0.024 mm respectively, which suggested that the method proposed had a high reliability. The findings of this study provide a new idea for the further development of the building crack monitoring field and is conducive to the accurate assessment of building safety.

“…[3] These methods can prove that the fingerprints found at the crime scene are identical to the perpetrator's fingerprints. [10] Thus, fingerprints can be one of the pieces of evidence as stipulated in Article 184 of the Criminal Procedure Code, namely, documentary evidence that can explain that the suspect or perpetrator committed the crime. So the fingerprints found at the crime scene are identical to the fingerprints stored in the police database.…”

This research is based on dactyloscopy at the crime scene and can be used as a clue for investigators in uncovering a criminal offense. This study aims to describe the function of dactyloscopy in the criminal investigation process and describe the dactyloscopy requirements to be evidence in the criminal investigation process. This type of research is normative law, and the approach method is normative juridical. The data technique collection is literature study and analysis of primary and secondary legal materials. This study indicates that fingerprints determine the perpetrators of crime, and fingerprints can be evidence of letters if proven by powder, brush, evaporation with sodium, and silver nitrate.

“…The fingerprint of a human being, is influenced by heredity and environment, exhibits a property of uniqueness [ 1 , 2 , 3 ], and has already become important evidence in criminal investigations and convictions [ 2 , 4 , 5 , 6 ]. Generally, there are three common types of fingerprint evidence at crime scenes: Impression (or indented) fingerprints, visible (or patent) fingerprints, and latent fingerprints [ 6 ].…”

The recognition of fingerprints has played an extremely important role in criminal investigations, due to its uniqueness. This paper reports on the recognition of sweat latent fingerprints using green-emitting, environment-friendly carbon dots prepared with DL-malic acid and ethylenediamine, and the exploration of impacting factors in the development process of fingerprints. The experiments showed that better fingerprint images could be obtained when the latent fingerprints are developed in green-emitting carbon dots with pH 9 for 30 min, at room temperature. The reported method was also effective for latent fingerprints on a variety of substrates, as well as for those water-immersed ones, where the developed fingerprint remained stable after long-term preservation. Furthermore, the fluorescent three-dimensional fingerprint image could provide direct and simple evidence on pressing habits. The objective of this paper was to present this method. The method may help to narrow the range of suspects during criminal investigations and in forensic science.
