Abstract: Disclosed are a novel tetrahydroisoquinoline compound, a method for preparing intermediates thereof, a pharmaceutical composition thereof and the use thereof. The tetrahydroisoquinoline compound of the present invention has a good inhibitory effect on phosphodiesterase (PDE4), and can be used in the prevention, treatment or auxiliary treatment of multiple diseases associated with the activity or expression of phosphodiesterase, especially PDE4-associated immune and inflammatory diseases, such as psoriasis and arthritis.

Abstract: An image processing device acquires at least two first images and down-samples the at least two first images to obtain at least two second images, where a first resolution of the at least two first images is higher than a second resolution of the at least two second images. By using the at least two first images and the at least two second images, the image processing device respectively determines a first depth map corresponding to the at least two first images under a limit of a first disparity threshold, and a second depth map corresponding to the at least two second images under a limit of a second disparity threshold, where the second disparity threshold is greater than the first disparity threshold. The image processing device then combines the determined first depth map with the second depth map to generate a combined depth map.

Abstract: An image processing device acquires at least two first images and at least two second images, where a resolution of the at least two first images is a first resolution, a resolution of the at least two second images is a second resolution, and the second resolution is lower than the first resolution. By using the at least two first images and the at least two second images, the image processing device respectively determines a first depth map corresponding to the at least two first images under a limit of a first disparity threshold, and a second depth map corresponding to the at least two second images under a limit of a second disparity threshold, where the second disparity threshold is greater than the first disparity threshold.
