“…This sheds a positive light on threat assessment practices, as research on other legal domains reveals that disagreement among professionals is not uncommon. For instance, forensic experts were found to produce inconsistent interpretations with regard to DNA evidence (Dror & Hampikian, ), fingerprints (Ulery, Hicklin, Buscaglia, & Roberts, ), and footwear (Majamaa & Ytti, ). Although such inconsistencies are worrisome, it should be acknowledged that consistent interpretations are not necessarily accurate.…”

When faced with threats of violence, it is of great importance to assess the risk for actual harm to occur. Over the last decades, this task has developed into a domain of its own and professionals have specialised in threat assessment. However, it is yet unknown whether professional experience affects the quality of threat assessments. The present study examined how threat assessment professionals (N = 44), university students (N = 44), and laypersons (N = 45) assessed the risk for violence in three fictitious cases. The assessments (i.e., assigning risk values to different pieces of information) were found to be strikingly similar across the three groups.Yet, professionals agreed more with one another on their assessments, and professionals identified more relevant (empirically supported) threat cues when given the opportunity to request additional information. These results suggest that threat assessment professionals know better than nonprofessionals what information to look for, and hence, they may contribute most in the process of gathering information to clarify the threat. Such knowledge can help to optimise the use of expertise, which may improve the quality of threat assessments. The current findings can be of value to those who consult threat assessment professionals, as well as to the professionals themselves.

“…Rathinavel To retrieve similar shoeprints, the main purpose of this study is to propose a method of core point alignment for pattern analysis of shoeprints. The four objectives include (1) to identify the contour of shoeprints and determine the core point; (2) to partition the circular regions based on the core point and extract features from these regions; (3) to analyze the textural patterns of the partitioned regions; and (4) to evaluate the retrieval performance among the different methods and settings.…”

“…According to the literature, the first case of shoeprint identification dates back to year 1786 [1]. Since then, shoeprint recognition has been generally used by the police for investigative purposes and by the courts as forensic evidence in criminal cases [2]. Shoeprint analysis and recognition can also provide valuable information to police investigators, as a link between different crime scenes may suggest possible suspects [3][4][5].…”

The purpose of this study is to propose a shoeprint retrieval method based on core point alignment for pattern analysis. The proposed method firstly detects contour points in a black-and-white shoeprint image. Those reliable contour points are selected to simulate the left and right sidelines of the shoeprint by curve fitting method. Subsequently, the most concave points along the left and right sidelines can determine the core point of the shoeprint, thereby partitioning the shoeprint into circular regions. Next, the Zernike moments of the circular regions are calculated for pattern description of each region. Finally, the Euclidean distance is measured to match the shoeprints with the same pattern. The highest = 0.726 is obtained from the first four Zernike moments with the radius = 90 pixels and three baselines. The experimental results also show that Zernike method in any orders always outperforms the compared moment invariants and GLCM method. This study has verified that the proposed method can effectively align the shoeprints for pattern comparison.
