استفاده از نمودارهای Finger print برای انتخاب وزن بچ مناسب
فرایند اختلاط یکی از مهم‌ترین مرحله‌هایی‌ست که هنگام تولید محصولات الاستومری، مواد خام باید از آن عبور کند. کیفیت فرایند پس از اختلاط، به یکنواختی و کیفیت آمیزه‌ی مخلوط شده بستگی دارد. هم‌چنین تولید اقتصادی محصولات لاستیکی، به‌طور مستقیم تحت تأثیر اختلاط است.هدف اصلی اختلاط فراهم آوردن آمیزه‌هایی‌ست با ویژگی‌های نهایی مناسب و مشخصه‌های پختی که هرچه بیشتر یکنواخت‌تر باشد. درهم‌آمیختگی و تو...
متن کاملTouch-Less Finger-Print Recognition
Our research is to overcome drawbacks in the current techniques for touch-less fingerprint recognition. We focus mainly image preprocessing, feature extraction and feature match. Each task analyzed by classical and up-to-date methods. Depending on the analysis, an integrated solution for demonstration of fingerprint recognition is developed. Our demonstration program is coded by MATLAB. To impr...
متن کاملFinger Knuckle Print Based Authentication
-In this paper, we investigate a new approach for personal authentication using Finger-Knuckle-Print through a novel texture descriptor, Local Directional Pattern (LDP). The image is encoded with Local Directional Pattern, which enhances the information as each pixel is represented as a binary LDP code. The Finger-Knuckle-Print is divided into smaller areas and LDP histograms are extracted from...
متن کاملContourlet Based Finger Print Matching
This paper describes a novel approach to finger print matching using a new mathematical transform: the contourlet transform. Contourlet improves traditional wavelet based approaches by incorporating a directional component. It finds a direct discrete-space construction and is therefore computationally efficient. In this paper, 2-D spectrum is divided into fine slices using iterated directional ...
متن کاملFinger Print Parameter Based Cryptographic Key Generation
A method is proposed for generation of unique cryptographic key which is generated using figure prints of the user, which are stable throughout person's lifetime. The proposed approach reduces the cost associated with lost keys, addresses non-repudiation issues and provides increased security of digital content. This approach has reduced the complicated sequence of the operation to generate cry...
