Most recent papers about visual cryptography for halftone images are dedicated to get a higher contrast decoded image. However, the hidden visual pattern often blends into the background image and leads to a confused image. In this paper, we propose an improved method for halftone image hiding. By using the proposed method, the background image can be eliminated and the hidden visual pattern ca...

Menurut Kementerian Pekerjaan Umum dan Perumahan Rakyat (2017), penyediaan akses sanitasi layak pada permukiman kumuh baru menncapai 10% dari total permikuman di Indonesia degan jumlah rumah mencapai 7,6 juta rumah. Kondisi tersebut perlu strategi pendekatan khusus untuk dapat meningkatkan yang terutama daerah perkotaan, khususnya bantaran sungai. Salah satu ekonomis mampu kesadaran masyarakat ...

Matrix manipulation programs are easily developed using a visual language. For signal processing, a graph of tasks operates on arrays. Each task iterates the same code on different patterns tilling these arrays. In this case visual specifications of dependencies between the pattern elements are enough to define an application. From the ARRAY-OL language developed by Thomson Marconi Sonar, we pr...

We present the design, implementation and performance evaluation of an algorithm devised for detection, extraction, and processing of visual code markers in images obtained via low-resolution cameras. The algorithm employs a myriad of techniques to locate, extract, and process the visual code markers for embedded binary data. The system performance has been assessed on a set of training images,...

Sparse code formation in the primary visual cortex (V1) has been inspiration for many state-ofthe-art visual recognition systems. To stimulate this behavior, networks are trained networks under mathematical constraint of sparsity or selectivity. Meanwhile, there is another line of research which emphasizes the role of lateral connections of neural networks in sparse code formation. Lateral conn...
