    paper:Convolutional Neural Networks for No-Reference Image Quality Assessment
    ideas:
        1.Taking image patches as input, the CNN works in the spatial domain without using
            hand-crafted features that are employed by most previous methods.

    ideas:
        1.in objective distortion part, a pixelwise objective error map is predicted 
            using the CNN model.
        2.in HVS-related part, model further learns the human visual perception behavior.

4.DeepBIQ
    paper:On the Use of Deep Learning for Blind Image Quality Assessment
    ideas:
        1.estimates the image quality by average-pooling the scores predicted on multiple 
            sub-regions of the original image
        2.fine-tuned for category-based image quality assessment.
