Considering the watermark as a noise, a watermark extraction model is proposed in this paper to enhance the correlation of Digimarc plug-ins in photoshop. First, an estimation of the original image for a watermarked image is obtained by TV (total variation) denoising model based on the partial differential equation. Second, watermark noise information is obtained by subtraction between the watermarked...
This work investigates pilocarpine trapped in a matrix diffusion-controlled drug delivery system using hydrophilic inserts of Poly(2-hydroxyethyl methacrylate) (pHEMA) to ensure an increased bioavailability of pilocarpine and prolong the length of time in which the medication remains in the eyes of the test subjects. The physical and chemical properties of pilocarpine were investigated to elucidate...
