Visitors\u27 Perception of Cirebon as a Tourist Destination-building to Promote the City

The problem identified in this study is how visitors\u27 perception and the image communication influenced the overall image of Cirebon as a tourist destination. This study was conducted by using structural equation modelling. The results of this study show that perception variable equation significantly affected the overall image variable, while the image communication variable did not significantly affect the overall image. On the other hand, the causal relationship equation shows that there is a significant relationship between the exogenous latent variable of perception and endogenous latent variable of Overall Image. While there is no relationship between exogenous latent variable of image Communication with endogenous variable of overall image. The result is expected to give recommendation to the local government to develop and promote tourism that at the end can put tourism to generate income for the city.DOI: 10.15408/etk.v11i1.187

Spontaneous Subtle Expression Detection and Recognition based on Facial Strain

Optical strain is an extension of optical flow that is capable of quantifying subtle changes on faces and representing the minute facial motion intensities at the pixel level. This is computationally essential for the relatively new field of spontaneous micro-expression, where subtle expressions can be technically challenging to pinpoint. In this paper, we present a novel method for detecting and recognizing micro-expressions by utilizing facial optical strain magnitudes to construct optical strain features and optical strain weighted features. The two sets of features are then concatenated to form the resultant feature histogram. Experiments were performed on the CASME II and SMIC databases. We demonstrate on both databases, the usefulness of optical strain information and more importantly, that our best approaches are able to outperform the original baseline results for both detection and recognition tasks. A comparison of the proposed method with other existing spatio-temporal feature extraction approaches is also presented.Comment: 21 pages (including references), single column format, accepted to Signal Processing: Image Communication journa

Three-dimensional perspective visualization

It was demonstrated that image processing computer graphic techniques can provide an effective means of physiographic analysis of remotely sensed regions through the use of three-dimensional perspective rendering. THe methods used to simulate and animate three-dimensional surfaces from two-dimensional imagery and digital elevation models are explained. A brief historic look at JPL's efforts in this field and several examples of animations, illustrating the evolution of these techniques from 1985, are shown. JPL's current research in this area is discussed along with examples of technology transfer and potential commercial application. The software is part of the VICAR (Video Image Communication and Retrieval) image processing system which was developed at the Multimission Image Processing Laboratory of JPL
