  • Publication number: 20230334629
    Abstract: A method for labeling an image object and a circuit system are provided. In the method, an object classification method is used to segment an image into one or more regions. Each of the regions can be classified into one classification assigned with a classification label. A depth estimation method is used to estimate a depth of each pixel of the image. Whether or not the depth of the pixel matches the classification of the region to which the pixel belongs is determined. When the depth of the pixel matches the classification of the region, a post-processing process is performed on the image based on weights assigned to the regions according to the classification label of the region. Conversely, when the depth of the pixel does not match the classification of the region, the pixel is regarded as noise that does not require the post-processing process.
