User Dependent Features in Online Signature Verification
In this paper, we propose a novel approach for verification of on-line signatures based on user dependent feature selection and symbolic representation. Unlike other signature verification methods, which work with same features for all users, the proposed approach introduces the concept of user dependent features. It exploits the typicality of each and every user to select different features fo...
متن کاملThe Graphology Applied to Signature Verification
In this paper we discuss automatic signature verification in the context of the graphology. Graphology is claimed to be useful for everything from understanding health issues, morality and past experiences to hidden talents, and mental problems. It is not restricted to this, though. Forensic document examiners use the concepts of graphology to examine handwriting in order to detect authenticity...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Rule Based Signature Verification and Forgery Detection
A rule based signature verification system has been devised based on Adaptive Network Based Fuzzy Inference System (ANFIS). The histogram of the angle differences along the signature trajectory is used as a descriptor of the signatures. We partition the histogram to obtain a number of rules, which is limited to 4 at a time. The performance of the proposed system is found to be satisfactory on t...
