Combing FSS technology with absorbing conception, an FSS radome with absorptive and transmissive characteristics is presented in the paper. It can transmit electromagnetic wave at around 20.5 GHZ. And below the transmission band, it can absorb energy at the frequency range of 5∼15GHz with Sit and S21 both less than −10dB, and with the absorption rate more than 80% (even up to 95% at some frequency...
An adaptive salient region detection method is proposed in this study, which combines LAB and RGB feature space and fused the color and contrast features. This algorithm first extracts the color feature of each image block in the LAB space and the contrast feature in the RGB space, and then fuses the color feature saliency map and the contrast feature saliency map using the principal component analysis...
