Automation is an open subject in DNA microarray image processing, aiming reliable gene expression estimation. The paper presents a novel shock filter based approach for automatic microarray grid alignment. The proposed method brings up significantly reduced computational complexity compared to state of the art approaches, while similar results in terms of(More)
– We present a robust watermarking method for still images using a discrete wavelet transform. The proposed scheme makes use of the image properties in order to make the watermark less perceptible to the HVS. The watermark is embedded in the coefficients of all subbands (except the LL subband), using a subband-adaptive thresholding scheme. We compare the(More)
The present paper describes a System on a Chip for microarray image processing together with the steps of a microarray experiment integrated in the proposed system. The system's reduced size and the hardware algorithms proved to overcome the disadvantages of the existing software for microarray image processing. FPGA technology was chosen for the(More)
