SEGMENTASI KARAKTER TULISAN TANGAN DENGAN FILTER OPTIMAL

Handwriting has been studied for a long time, because of its widespread use as a means for human-to -human communication. The variability of handwriting, due to differences in cultures, writer styles, alphabets or fonts, make it an interesting problem in the field of pattern recognition. For cursive writing, segmentation is necessary within strokes since several characters can be made with one stroke. Cursive script recognition is difficult because several characters can be written with a single stroke. Owing to the difficulty of this problem, there have been many serious efforts toward obtaining a solution. In this paper, we propose and experimentally study an on-line handwriting segmentation system, we pay attention to the preprocessing stage. This step is necessary because our system considers on-line handwritten specimen as a signal with dynamic information, that can be split into components, which are in turn divided to elemental movements, called strokes. The objective of segmentation is to divide complex handwriting pieces into simpler ones, in order to reduce input pattern variability and thus simplify the classifier structure. In this work initial data are isolated characters composed of one or more components, which are to be segmented into strokes. There are 25 stroke to segment 26 letters in English. We propose optimal filter to smoothing the signal of the character. The segmentation algorithm is based on the maximum and minimum speed analysis of the pen's movement. The percentage of success depends on the quality of the handwriting. The vibration of the hand may affect handwriting quality. In the case of26 letters, the success rate is 73

PEMBUATAN DENAH PANDUAN KAMPUS D UNIVERSITAS GUNADARMA PADA TELEPON GENGGAM MENGGUNAKAN J2ME

Dilain pihak kemajuan teknologi telepon genggam sudah dapat memungkinkan pencarian informasi melalui telepon genggam. Sehingga informasi yang tepat, cepat dan dapat diakses kapan saja menjadi terpenuhi. Berdasarkan hal tersebut pada penelitian ini dibuat program aplikasi untuk menampilkan denah lokasi pada telepon genggam yang dikhususkan untuk kampus D Universitas Gunadarma. Tujuan dari penelitian ini adalah mempermudah dalam rangka pencarian lokasi ruangan di kampus D Universitas Gunadarma melalui telepon genggam, selain itu juga dapat mengukur jarak denah, memberikan informasi keterangan ruangan dan menampilkan detail ruangan. Agar aplikasi ini dapat berjalan dibanyak telepon genggam yang mendukung Java, pada proses pembuatannya menggunakan bahasa pemrograman J2ME (Java 2 Micro Edition). Berdasarkan pada hasil uji coba, menunjukkan bahwa aplikasi pencarian lokasi ruangan kampus D Universitas Gunadarma berhasil diimplementasikan dengan dukungan bahasa pemrograman Java

Pencarian Citra Berbasis Web Berdasarkan Pada Keyword dan Karakteristik Citra

Search engine has been developed to assist users in finding information easier, including images in the internet. There are several images search engine working on the internet, such as google image search, which is searching to several URL, using text or color similarity as the query. Visually, the results obtained from these engines are sometimes irrelevant or not sorted

ANALISIS PENELUSURAN TEPI CITRA MENGGUNAKAN DETEKTOR TEPI SOBEL DAN CANNY

Salah satu tahapan utama dalam pengolahan citra adalah proses pendeteksian tepi, dengan danya proses ini batas antara objek dengan latar belakang dapat ditentukan dengan baik. Banyaknya metode pendeteksian tepi yang ada saat ini dapat menimbulkan keraguan dalam pengambilan keputusan penggunaan metode yang tepat dan sesuai dengan kondisi citra yang dideteksi. Berdasarkan maslah tersebut, penelitian ini bertujuan melakukan analisis terhadap kinerja pendeteksi tepi operator Sobel dan operator Canny, sehingga dapat memberikan informasi yang akurat mengenai kinerja operator pendeteksi tepi. Hasil eksperimen menunjukkan bahwa operator Sobel kurang tepat jika digunakan untuk mendeteksi tepi citra yang mengandung noise, sedangkan operator Canny dapat mereduksi noise dengan baik

Psychometrics and population norm of the Chinese (HK) SF-36 Health Survey_version 2

Objective: To establish the psychometric properties and norm of the Chinese (HK) SF-36 version 2 Health Survey for the adult population in Hong Kong (HK) to facilitate its application and interpretation. Design: A cross-sectional random telephone survey of the general adult population. Subjects: 2410 Chinese adults randomly selected from the general Chinese adult population in Hong Kong. The mean age of the subjects was 42.9 (S.D. 17.3) years, 48% were men and 38% had one or more chronic disease. Main outcome measures: Responses to the SF-36v2 Health Survey questions were extracted. Item-scale correlations, internal and test-retest reliabilities, and the factor structure of the SF-36v2 Health Survey scores were analysed. The SF-36v2 Health Survey scores were calculated by the standard algorithm to establish the population norm. Results: All items had 100% scaling success indicating discriminant validity. Internal consistency and test-retest reliabilities of all scales were good (coefficients 0.66 to 0.89). The hypothesized two-factor structure underlying construction of the physical and mental health summary scales was confirmed. The psychometric properties of the SF-36v2 Health Survey were generally better than version 1. There were significant differences in the population norms between versions 1 and 2 of the Chinese (HK) SF-36 Health Survey, especially in the role-physical and role-emotional scales. Conclusion: The Chinese (HK) SF-36v2 Health Survey is valid and reliable for measuring HRQOL of Chinese adults in Hong Kong, and population norm is now available to support the interpretation of its scores.published_or_final_versio

Brief problem-solving treatment in primary care (PST-PC) was not more effective than placebo for elderly patients screened positive of psychological problems

Objectives To evaluate whether screening followed by brief problem-solving treatment by primary care doctors (PST-PC) could improve health-related quality of life (HRQOL) and reduce consultation rates in the elderly. Design A single-blind randomized placebo controlled trial (RCT). Setting Two government funded primary care clinics in Hong Kong. Participants Two hundred and ninety nine Chinese patients aged 60 years or over, with positive screening scores for psychological problems by the Hospital Anxiety and Depression Scale (HADS). Interventions One hundred and forty nine subjects were randomized to receive brief PST-PC from primary care doctors (treatment) and 150 to group video-viewing (placebo). All subjects were followed up by telephone at 6, 12, 26 and 52 weeks. Main Outcome Measures Changes in SF-36 HRQOL scores, HADS scores and monthly consultation rates were compared within and between groups. Results Study completion rates were 69-71%. There was significant improvement in the SF-36 role-emotional (RE) and mental component summary (MCS) scores at week 6 in the PST-PC group but not in the placebo group. Several SF-36 scores improved significantly in the placebo (video) group at week 6-52. Mixed effects analysis adjusting for baseline values and cofounders did not show any difference in any of the outcomes between the PST-PC and placebo (video) groups. Conclusions Screening followed by brief PST-PC was associated with a short-term improvement in HRQOL in Chinese elderly patients screened positive of psychological problems, but the HRQOL benefit was not greater than those found in the placebo group who participated in group-viewings of health education videos. © 2009 John Wiley & Sons, Ltd.postprin
