  • The palm print recognition is the most reliable authentication method in the biometrics. In this paper, using the efficient segmentation of the palm print region we propose the method of enabling the palm print recognition as the same method applicable to the finger print recognition. To achieve this, we propose the image processing procedures of the palm print segmentation and the feature extraction. We compare the matching result after extracting the features for the finger print and the palm print.

  • This paper is to propose the palm print recognition system using wavelet transform. The palm print is frequently used as the material for the biometric recognition system such as the finger print, iris, face, etc. Since the palm print has lots of properties which include principle line, wrinkles, ridge and so forth, the ways of the implementation of the system are various. In this paper, at first, the palm print image is acquired and then some level of wavelet transform is performed. The coefficients become to be some blocks size of M by N after divided into the horizontal, vertical, diagonal components each level. The mean values, which are calculated with values of each block, are used as the feature vector. To compare between the stored template and the acquired vectors, we adopt the PNN (Probability Neural Network) method.

  • In Sasang constitutional medicine, the classification of Sasang constitutional types (Tae-Yang, Tae-Eum, So-Yang, and So-Eum) is important for the treatment. There are some problems with the methods used for classifying Sasang constitutional types; old methods such as pulse-palpation are not considered objective and recent methods such as immunohematology are considered expensive, painful and time-consuming. To overcome these problems, a body measurement and finger prints analysis were performed. The purpose of this study was to determine whether the palm prints and the palm creases could be helpful in classifying Sasang constitutional types. Thus, we looked for characteristics of the palm prints and the palm creases according to Sasang constitutional types. Before analyzing the palm prints and palm creases, 760 Korean (465 males, 295 females) were surveyed using two kinds of questionnaires for classifying Sasang constitutional types. As there were no Tae-Yang individuals, we were only able to identify the characteristics of the palm prints and the palm creases for Tae-Eum (288 persons), So-Yang (193 persons), and So-Eum (279 persons) individuals. In this study, the terminal points of D, closed crease, and open crease seemed to be helpful in classifying Tae-Eum and So-Eum individuals. Terminal point 11 and closed crease were frequent in Tae-Eum individuals; whereas, terminal point 7 and open crease were frequent in So-Eum individuals. Therefore, the palm prints and the palm creases seem to contribute to the classification of Sasang constitutional types.

  • In this paper, we study image clustering without labeling using machine learning techniques. We proposed an unsupervised machine learning technique to design an image clustering model that automatically categorizes images into groups. Our experiment focused on inception convolutional neural networks (inception V3) with k-mean methods to cluster images. For this, we collect the public datasets containing Food-K5, Flowers, Handwritten Digit, Cats-dogs, and our dataset Rice Germination, and the owner dataset Palm print. Our experiment can expand into three-part; First, format all the images to un-label and move to whole datasets. Second, load dataset into the inception V3 extraction image features and transferred to the k-mean cluster group hold on six classes. Lastly, evaluate modeling accuracy using the confusion matrix base on precision, recall, F1 to analyze. In this our methods, we can get the results as 1) Handwritten Digit (precision = 1.000, recall = 1.000, F1 = 1.00), 2) Food-K5 (precision = 0.975, recall = 0.945, F1 = 0.96), 3) Palm print (precision = 1.000, recall = 0.999, F1 = 1.00), 4) Cats-dogs (precision = 0.997, recall = 0.475, F1 = 0.64), 5) Flowers (precision = 0.610, recall = 0.982, F1 = 0.75), and our dataset 6) Rice Germination (precision = 0.997, recall = 0.943, F1 = 0.97). Our experiment showed that modeling could get an accuracy rate of 0.8908; the outcomes state that the proposed model is strongest enough to differentiate the different images and classify them into clusters.

  • A grip impression is evidence of contact between the assailant and victim in a case. The shape of the grip impression can be analyzed to reconstruct which part of the palm it contacted. This study explored whether the grip impression left on cotton, nylon, and polyester fabrics can be identified by vacuum metal deposition (VMD). The latent grip impression developed by VMD had limitations in personal identification, but a new possibility was found that could be used as evidence for crime-scene reconstruction.

  • 1. Background : Sasang Constitutional Medicine divides mankind into Taeyangin(太陽人), Taeumin(太陰人), Soyangin(少陽人) and Soeumin(少陰人) according to appearance, moral nature and characteristic of constitutional symptoms, and it is a medical science to study about different treatment for each constitution. In Sasang Constitutional Medicine, diagnosis of constitution was so important that we had the necessity of studying constitutional diagnostic method which had presented wholly and intuitively in Dongyi Soose Bowon(東醫壽世保元) with objective and analytic thinking. There were several attempts to classify Sasang Constitutional Types through morphological investigation of each parts of body. The one of them was to use measuring the body. In this study, we purposed to make clear whether the analysis of fingerprints and palm, one of the physical anthropologic methods would be helpful to classify Sasang Constitution. 2. Method : After practicing Questionnaire I and QSCC(Questionnaire of Sasang Constitution) II from 347 healthy Korean adults(242 males and 106 females), we analyzed fingerprints and palm prints of 208 people(142 males and 66 females) who were classified same constitution from two questionnaires. We analyzed the types of fingerprints according to the number of triradius and counted the number of dermal ridges from fingerprint center to triradius. We found triradius in the lower part of each finger and analyzed the courses of dermal ridges and counted the number of dermal ridges between each triradius. We mesured angle atd, and then researched relationship between fingerprints, palm prints and Sasang Constitution. 3. Result and Conclusion : The results of Sasang Constitution analysis of 208 Korean adults showed 76 Taeumin(36.5%), 81 Soeumin(39.0%) and 51 Soyangin(24.5%). The analytic results of fingerprints and palm prints are as follows : The types of fingerprints were helpful to sort Taeumin and the types of palm prints were helpful to sort Soyangin and Soeumin especially. In addition, the number of dermal ridges in fingerprints and palm prints were helpful to sort Soyangin. Fingerprints and palm prints have characteristic in each constitutions, so the investigation of fingerprints and palm prints seems to helpful to classify Sasang Constitution. We are planning to report fingerprints and palm prints of more subjects.

  • In this paper, we present a grasp planning method using grasp taxonomy and object primitives. Our grasp taxonomy includes newly defined grasp methods such as thumb supported pinch and palm supported pinch, to enhance grasp robustness. On the target surface, locations of finger-print that will be contacted by the robot fingers are sampled. The sampling is made to be consistent to the grasp taxonomy, called preformed grasps, matched to the target object. We perform simulations to examine the validity and the efficacy of the proposed grasp planning method.

  • "Aloha" is the Hawaiian word that extends the warmth friendliness, and pride of the Hawaiian people to their island's visitors. The aloha shirt truly symbolizes aloha sprit to islanders and visitors alike. The earliest foreign settlers in the Hawaiian Islands were the Chinese and Japanese. They brought with them their myriad talents and trades, among them the art of tailoring. In July of 1936, a shirtmaker named Ellery J.Chun coined the term "Aloha Shirt" an apt characterization for such an eloquent garment. He was the first to make the shirt on a commercial basis. The shirt sold for as little as a dollar in Chun's own King-Smith store. The genuine aloha shirt is now regaled as a work of art and avidly sought out by collectors. When tourism came to Hawaii in the late 1930s, these unusal shirts were among the first thing that visitors had to have. Local designers and tailors worked quickly to meet the demand and began to expand the range of decoration to include palm trees and romantic beaches, tropical jungles and volcanoes, exotic flowers and scenes from polynesian legend. Therefore the aloha shirt had been born. The functional use of creative colors and amazing artistic renderings in these shirts certainly capture the simplicity and sprit of Hawaii. Aloha shirt is dress that display mystery and charm of Hawaii and cultural symbol of condensed Hawaiian mind. Furthermore, the innocence with which Hawaiians formerly translated their life and heritage onto fabric ranks these shirts with the finest of American folk art. Aloha shirt is made from cotton, silk, rayon in present and past. Most important design element of Aloha shirt is print pattern. Main print pattern of Aloha shirt are all over pattern, horizontal pattern, border pattern, Japanese pattern, picture pattern and back panel pattern. In this study I investigate the design characteristics and development process of aloha shirt.
