Is that Innovation? Assessing Examples of Revitalized Economic Dynamics among Clusters of Small Producers in Northern Vietnam

This paper addresses the question whether innovation is within reach for small enterprises in developing economies by studying four cases of new technologies, products and business practices in traditional craft in Northern Vietnam. The paper starts with reviewing definitions of innovation since Schumpeter. It concludes that newness, value creation and process are time and again considered as the key-elements of innovation. Innovation, hence, may be summarized as the process of introducing something new that creates value. Subsequently, this theoretical definition is operationalized into an innovation assessment instrument and applied in the aforementioned cases. The instrument verified the occurrence of innovation in three out of four cases of small producers' clusters in Northern Vietnam. The entrepreneurs managed to implement innovation on their own strength and upon their own initiative. This provides evidence that small enterprises in developing countries are indeed able to take part in the process of increasing competitiveness through innovation.innovation, small enterprises, clusters, value chains, Vietnam

Quality Adaptive Least Squares Trained Filters for Video Compression Artifacts Removal Using a No-reference Block Visibility Metric

Compression artifacts removal is a challenging problem because videos can be compressed at different qualities. In this paper, a least squares approach that is self-adaptive to the visual quality of the input sequence is proposed. For compression artifacts, the visual quality of an image is measured by a no-reference block visibility metric. According to the blockiness visibility of an input image, an appropriate set of filter coefficients that are trained beforehand is selected for optimally removing coding artifacts and reconstructing object details. The performance of the proposed algorithm is evaluated on a variety of sequences compressed at different qualities in comparison to several other deblocking techniques. The proposed method outperforms the others significantly both objectively and subjectively
