Abstract: A system and a method for automatically identifying mitosis in H&E stained breast cancer pathological images are provided, belonging to the technical field of digital image processing, and including an input image preprocessing module: cutting an original picture according to a predetermined patch size, and performing a data enhancement by means of picture flipping, rotation, and the like; and a segmentation module: training a segmentation network by cutting patches in a training set, cutting data of a test set according to a corresponding size and sending to the segmentation network to obtain a patch-level segmentation result, and then reconstructing a segmented result into an image belonging to an original size according to patch coordinate information intercepted in a preprocessing stage of it.

Abstract: Disclosed is an LED packaging structure using a distant fluorescent powder layer and a manufacturing method thereof. A fluorescent powder layer (10) with a recessed cavity cover structure is used in the packaging structure. A group of dies for manufacturing the fluorescent powder layer are specifically designed in the present invention. The fluorescent powder layer manufactured by using the dies has a regular structure and an even thickness. The fluorescent powder layer and a substrate (30) form a closed cavity for accommodating a chip (20) on the substrate, the cavity is vacuum, and the effect of distant fluorescent powder coating can be achieved. The manufacturing method can be also used for batch manufacturing of the fluorescent powder layers, and repeated adhesive dispensing for each chip in the traditional batch packaging process of the fluorescent powder layers is avoided, thereby improving the LED packaging efficiency.
