This paper proposes a new feature descriptor named as Local Primitive Code (LPC), which exhibits impressively discriminative capability on various face datasets. Essentially, LPC descriptors are somewhat like filter banks of Gaussian derivatives to capture multi-scale and multi-orientation image local textures but meanwhile enables faster feature extraction. It employs a framework composed of two...
We have designed and fabricated a low cost THz band pass filter based on a plastic substrate. The filter shows excellent performance for THz applications. We have also investigated its possible application to biological sensing.
