Perception of Foreign Tourists to Karawo Embroidery Handicrafts in Gorontalo Tourist Destinations

The purpose of this study was focused on knowing the perceptions of tourists, both foreign tourists, about the craft of Karawo embroidery in Gorontalo Tourism Destinations. This research method using a quantitative approach itself is carried out using a questionnaire given to the public and tourists who visit the Karawo embroidery craft center. The sampling technique in this study used a non-probability or non-random sample selection technique. The results showed that the quantitative approach itself was carried out using a questionnaire given to the public and tourists who visited the Karawo embroidery craft center. The sampling technique in this study used a non-probability or non-random sample selection technique. The results of this study indicate that the Karawo embroidery craft has the potential to be developed as a tourist attraction in Gorontalo Province. Analysis of the attractiveness and perceptions of tourists who visit the Karawo embroidery craft center as well as the local community provide direction on the development of tourist attractions that are related to cultural aspects. The perception of foreign tourists in general gives a positive value to Karawo embroidery and argues that Karawo embroidery is unique from the manufacturing process and has its own characteristics with very beautiful motif designs.

Intelligent Image Watermarking Using Genetic Programming

Multimedia applications are becoming increasingly significant in modern world. The mushroom growth of multimedia data of these applications, particularly over the web has increased the demand for protection of copyright. Digital watermarking is much more acceptable as a solution to the problem of copyright protection and authentication of multimedia data while working in a networked environment. In this thesis a DWT based watermarking scheme is proposed. Wavelet transform is used because it has a number of advantages over other transforms, such as DCT. · It has multi-resolution hierarchical characteristics, and lower resolution embedding and detection which are computationally inexpensive. · The presentation of the image because of the hierarchical multi-resolution properties of the transformation is well-suited for applications where the multimedia data is transmitted regularly, as such in the application of video systems, or applications in real time. · Wavelet transform is closer to HVS contrast to DCT. For this reason, the range of artifacts introduced by wavelet is less infuriating as compared to DCT. For better imperceptibility, the watermarking technique should support a vision model which integrates various masking effects of the Human Visual System (HVS), to embed watermark in an invisible manner. For HVS we have used Watson’s Perceptual Model of JPEG2000. The basic aim of perceptual coding is, to conceal the watermark below the detection threshold. This can be obtained by making use of the HVS and JND threshold. The watermarking technique based on this model resists all types of common signal processing operations and many geometric attacks but unfortunately was not resistant against rotation. Keeping in mind this we explored Morton scanning. Morton scanning is used to
