PENERAPAN DIGITAL WATERMARK SEBAGAI VALIDASI KEABSAHAN GAMBAR DIGITAL DENGAN SKEMA BLIND WATERMARK

Digital watermarking is an important field of technological development that has now grown in the digital era. Digital era encourage the spread digital images on internet by the websites with a large scale. On the other hand, digital images are objects that are very easy to change or manipulate, and even copied irresponsibly. Meanwhile it is very difficult to prove the image has been changed by existing equipment at this time, and it is difficult to prove its ownership. This is an important issue, when the image is one of the evidences for legal cases, news reporting and medical filing, where the image must be ensured that the digital image is not subject to change or manipulation. In this paper, we present the application of digital watermarking to authentication and ownership validation of digital image so the image can be ascertained its validity. This research applies blind watermark scheme by using secret key that inserted at least-significant bits (LSB) of host image therefore the watermark is invisible watermark. The result of watermarked image has a small decrease in quality with the mean value of PSNR and MSE about 34.08 and 14.62

Moving Object Detection under Complex Environment using Spatio-Temporal Evaluation Methods

Mendeteksi dan melacak objek merupakan proses utama dalam otomatisasi video analisis. Kebanyak penelitian terkait deteksi dan pelacakan objek didapat dari memisahkan foreground dan background dengan mengandalkan informasi dari temporal yang terbatas. Namun pada kenyataanya saat video diambil di luar lingkungan, gangguan dari lingkungan seperti bayangan daun dan pohon kecil yang tertiup angin, tidak dapat dihindari. Hal tersebut mengakibatkan background menjadi sangat dinamis dan mengacaukan pendeteksian objek. Dalam mengatasi permasalahan background yang dinamis, perlu adanya evaluasi terhadap pola gerak objek secara simultan. Penelitian terkait Moving Object Detection sampai saat ini terfokus pada perbaikan segmentasi foreground dan background. Sehingga sistem akan membutuhkan tambahan proses yang signikan dalam melakukan pelacakan objek. Pada penelitian ini, kami mencoba meningkatkan fungsi Moving Object Detection hingga pada pelacakan object dengan mengusulkan prosedur evaluasi dari spatio-temporal. Spatio-temporal akan dievaluasi dari dua arah: vertikal dan horisontal. Dengan memanfaatkan informasi dari arah vertikal dan horisontal, prosedur kami berhasil mereduksi proses evaluasi yang selama ini menggunakan keseluruhan pixel pada setiap frame. Selain itu, hasil dari percobaan menunjukkan bahwa prosedur kami mampu mendeteksi dan sekaligus mendapatkan lintasan dari object dengan recall : 0:65, precision: 0:75, f-measure:0:64 dan recognition rate berkisar 0:76.
