A 79-year-old male with a positive fecal occult blood test result underwent total colonoscopy, which revealed a 15-mm-semipedunculated polyp in the rectum. The polyp appeared to be an adenoma using narrow-band imaging observation in magnifying endosc

It is widely known that deep learning using a deep neural network (DNN) provides high performance in the fields of image recognition and image generation. On the other hand, DNN is composed of a huge number of filters, and the amount of information t

This paper proposes a quantization matrix design method for sparse representation-based image coding. In the proposed method, we define the complexity of the atoms in the dictionary designed by K-SVD as a simple total variation, and design a quantiza

In this paper, we propose a new method to apply deep learning to bidirectional interframe prediction in video compression. The novelty of the proposed method is to create an interpolated frame by the geometric transformation matrices estimated by CNN

Higher frame-rates are essential in achieving more realistic representations. Since increasing the frame-rate increases the total amount of information, efficient coding methods are required. However, the statistical properties of such data, needed f

We developed an MPEG-2 transcoding method on the basis of a two-tiered quantizer matrix that reduces re-quantization noise. The proposed method changes the quantization matrix to decrease the re-quantization noise, instead of changing the value of th
