Abstract

Abstract. In the sequential image compression process there are two compression processes known as intraframe and interframe compressions. This paper focuses on intraframe compression on an image sequence by using the 14 Biorthogonal wavelet. Intraframe compression utilizes spatial redundancy within a frame. This happens because there is a correlation between a pixel with its neighboring pixels. This research uses different changes between frames in sequential images by moving the camera, and shifting objects in the middle. Then each sequential image is tested by using the 14 Biorthogonal wavelet toward its PSNR and compression ratio (%). The results of  the research can be concluded that the Biorthogonal 2.4 has the highest PSNR. As for the compression ratio, they show that the Biorthogonal 3.1 produces the highest compression ratio (%).Keywords: Sequential image, intraframe compression, compression ratio, PSNR, wavelet Abstrak. Pada citra sekuensial dikenal dua proses pemampatan yaitu pemampatan intraframe dan pemampatan interframe. Pada makalah ini lebih difokuskan pada pemampatan intraframe dari suatu citra sekuensial yang menggunakan 14 wavelet Biorthogonal. Pemampatan intraframe memanfaatkan redundansi spasial yang terdapat dalam suatu bingkai. Hal ini disebabkan karena adanya korelasi antara sebuah piksel dengan piksel di sekitarnya. Penelitian ini menggunakan perubahan antar bingkai pada citra sekuensial, yaitu kamera yang bergerak dan obyek di tengah bergerak. Kemudian setiap citra sekuensial diuji dengan 14 wavelet biorthogonal terhadap PSNR dan prosentase rasio kompresinya. Dari hasil penelitian dan pembahasan dapat ditarik beberapa kesimpulan, yaitu pada pemampatan intraframe wavelet Biorthogonal 2.4 menghasilkan PSNR tertinggi. Sedangkan untuk porsentase rasio kompresi terlihat bahwa Biorthogonal 3.1 menghasilkan rasio kompresi tertinggi.Kata Kunci: citra sekuensial, pemampatan intraframe, prosentase rasio kompresi, PSNR, gelombang singkat

Abstract

The technological era in business competition requires creativity and innovation to create a successful company. CRM (Customer Relationship Management) is a system that aims, among others, to provide improving relations between the company and customers, so that the realization of integrated information is used to produce optimal services and obtain useful customer information so that customer needs can be met and encouraged to loyalty. In addition, CRM can be useful to improve efficiency and reduce operational costs of PT. Hasjrat Abadi (Tendean Branch). To support the success of PT. Hasjrat Abadi (Tendean Branch), this study will examine a CRM system to be applied to PT. Hasjrat Abadi (Tendean Branch) by integrating it into the Technology Acceptance Model (TAM) as a model that can be analyzed and understood so that later it can influence customers in the use of technology as an information system by using informational system variables. In this research, user acceptance has been reviewed based on 4 variables in TAM itself. PT. Hasjrat Abadi (Tendean Branch) has a problem where there is still a lack of customer demand for TOYOTA products. Therefore, the implementation of the TAM system for CRM will be pursued so that it can identify the customers of PT. Hasjrat Abadi (Tendean Branch) Manado who want to buy products from PT Hasjrat Abadi (Tendean Branch) Manado, and increase the selling value of the product.
