Abstract: An image analysis method is provided. In the image analysis method, a to-be analyzed image is inputted into a region-based convolutional neural network (RCNN) model to obtain a masked image outputted from the RCNN. The center of a masked object in the masked image is calculated. The center is regarded as an origin of coordinate and the farthest coordinate point from the origin of coordinate in each of the four quadrants relative to the origin of coordinate are searched. The image analysis block is generated for each of the farthest coordinate points. The post-processing is performed on the image analysis blocks to obtain an object range.

Abstract: The invention provides a light source optimization apparatus including a storage apparatus and a processor. The storage apparatus stores a plurality of modules. The processor is coupled to the storage apparatus and configured to execute the plurality of modules. The plurality of modules include a critical pattern module and a light source optimization module. The critical pattern module retrieves critical pattern data. The light source optimization module executes an ant colony optimization (ACO) algorithm according to a preset parameter to adjust an initial light source image to generate an output light source image, and the initial light source image corresponds to the critical pattern data.
