For evaluating the match of the 3D and 2D facial images in the same person (a match), the 3D facial image obtained from 10 subjects was compared to the 2D oblique facial image of the same subject ten times, yielding 100 superimpositions. In the case of different persons (non-matching), the 3D facial images of 10 subjects were each compared to the 2D facial images of other 9 subjects, yielding 90 superimpositions. As a matching criterion, the sum of the values of the average perpendicular difference of the facial outlines and the average point-to-point difference between the corresponding landmarks was used (abbr.: average difference). The range of the average difference was 3.6-6.3 mm for the matching person and 5.8-15.3 mm for non-matching persons, respectively. The average difference and percentage error at the FP/FN crossover point were 6.0 mm and 3.2 percent. In this experiment, it was concluded that the morphometric matching method would be applicable to the identification of blurred images of Caucasian faces.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124132680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yagi","doi":"10.3408/JASTI.3.1","DOIUrl":"https://doi.org/10.3408/JASTI.3.1","url":null,"abstract":"Two experiments examined the influence of differences between memory representation and the content of critical items presented visually for detection accuracy in a guilty knowledge test. In Experiment 1, skin conductance responses (SCR) of 12 subjects were measured under three conditions. In each of two conditions, one of two pictures that differed in the degree of match to the stimulus memorized previously was used as a critical item, while the identical picture was used in another condition. The results indicated that detection accuracy on the item relatively similar to the memorized material was lower than that of the item identical to representation. Both items could be detected. However, when the critical item was dissimilar to the previously memorized stimulus, the rate of correct detection did not indicate a significant increase above chance expectancy. In Experiment 2, two types of pictures, identical and dissimilar pictures, were used as critical items and names of which were also presented orally. There was another condition where the critical item was presented only orally. Skin conductance responses of 12 subjects were measured. In the dissimilar picture condition, detection accuracy was lower than that of the identical picture condition, but the rate of correct detection was significantly greater than a chance level. There was no statistically significant difference on detection accuracy between the dissimilar picture and oral conditions. The results of these studies showed that 1) examiners shoud use critical items which were as similar to memory representation of the subjects as possible, and 2) there could be a case that was successful to detect deception even if the critical items were not identical to memory representation.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124748515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still sometimes a laborious task to rapidly distinguish a criminal from a number of suspects using the existing current facial identiˆcation system. Therefore in this study new software, which automatically adjusts the orientation of 3D face images in the database, was designed and its availability was experimentally evaluated as a preliminary step of an automatic face image identiˆcation system. From a total 5000 superimpositions of the 2D face images of 50 subjects which were compared automatically with the 3D face images of 100 suspects, only 18 face images of suspects (0.4) showed inadequate orientation compared to their corresponding 2D face images for recognition purposes. From this experiment, it is concluded that the software developed will be applicable to the automatic adjustment of facial orientation in the 3D face image database and this is anticipated to improved the e‹ciency of policing in Japan as 3D imaging systems are deployed.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122870222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The four characteristics used for the quantification of hair form included a basic characteristic (5 categories), an additional characteristic (4 categories) and 2 peculiar morphologies (3 categories). The hair forms of Japanese head hair were expressed by 448 combinations of these 12 categories. In addition, two numerical features were used as numerical data related to hair form as follows; the length and number of curves facing an assumed straight-line drawn between the tip and root ends of a hair image copied on the paper. This numerical feature was newly designed for this study. For confirming the availability of hair form for a hair comparison, the inter-individual comparison of Japanese males was investigated by a discrimination analysis using 13 variables, 11 values obtained by quantification and 2 numerical features. Head hairs from Japanese males were classified with a high level of discrimination between 2 individuals based only on hair form. Since the screening of evidential hair samples was investigated by a cluster analysis using 13 variables, in an experimental model of 40 evidential hair samples derived as an extra hair sample from 8 individuals, hair samples from 8 individuals were successfully discriminated using a cluster analysis. It was confirmed that a morphological examination represents an important tool for use in forensic hair comparison and that hair form is indispensable for interpreting the similarity of morphological features between known control hairs and evidential hairs.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124662833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 3D physiognomic measurement apparatus is composed of a detector comprised of two laser scanner devices and two CCD cameras, an image encoder interfaced to a computer, and two TV monitors. The 3D analysis apparatuis comprises of the following five parts : a host computer, an image processing unit, a CCD camera for inputting facial photographs of a perpetrator, a video image mixing unit and a TV monitor. The 3D surface morphology of a suspect face is measured with the detector using three representative parameters of the facial surface, that is, the illumination, brightness and depth data. The parameters are measured and then stored on the floppy disk. The 3D facial image of the suspect is superimposed on the facial photograph of the perpetrator on the monitor using the 3D analysis apparatus. In order to assess the reliability of the facial photographic identification with this system, the face-to-face superimposition was experimentally investigated. An oblique facial photograph of a target person was compared to the 3D facial image of the target person and other 19 examinees. The 2D facial photograph of the target person revealed a good match with the 3D facial image of one of the subjects, giving a positive identification. This system will be a useful tool for forensic photographic comparison and will prove very effective in court because the video superimposition of two faces can be performed under the same facial orientation.","PeriodicalId":134327,"journal":{"name":"Japanese Journal of Science and Technology for Identification","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134433854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
