Image features obtained from the DCNN and clinical data corresponding to cytological images were given to the classifier. Then, these features were reduced dimensions by PCA. 4096 features before the fully connected layer were extracted. Next, image features were extracted from cytological images using VGG-16 model pretrained on the ImageNet dataset. And then, we collected personal clinical data (age, gender, smoking status, laboratory test values, tumor markers and so on) corresponding to cytological images. The original microscopic images were first cropped to obtain images with resolution 256 × 256 pixels. First, the cytological images were collected. We aimed to develop of classification method of lung tumor type by combining cytological images and clinical record. In this study, we aimed to improve the classification accuracy of lung cancer type by combining cytological images and electronic medical records. In this study, we focus on liquid-based cytology images and clinical record. However, its classification accuracy is approximately 70%, therefore improvement in accuracy is required. In previous study, automated classification method for lung cancers in cytological images using a deep convolutional neural network (DCNN) was proposed. Recently, as chemotherapy has advanced, it is important to accurately diagnosis the histological type (adenocarcinoma, squamous cell carcinoma and small cell carcinoma). The visual outputs indicate that the proposed network convincingly eliminates the reflection and produce sufficient transmitted layers as compared to the previous methods. The experimental results demonstrate that the proposed method outperforms the existing approaches in both PSNR and SSIM. Since it is intractable to obtain the ground-truth transmitted layer in real images, a dataset with synthetic reflection is considered for quantitative evaluation.

Thus, by adding this information to both generative and discriminative networks, the generator focuses on the transmitted layer and the discriminator will be able to estimate the local consistency of the restored areas. The DoF is formulated by using image statistics and indicates the focused region of image. In this paper, to solve this problem, a Generative Adversarial Networks guided by using Depth of Field (DoF) is proposed. In fact, while human vision can automatically focus on the transmitted object, basic deep neural networks even have a limitation to learn the attentive mechanism. Better discrimination of the subjects by the HMM-based classification of the eye movement data corresponded to lower face recognition scores by the subjects, suggesting that individually consistent eye movement patterns may lower the face recognition performance by humans.Įliminating reflections on a single-image has been a challenging issue in image processing and computer vision, because defining an elaborate physical model to separate irregular reflections is almost impossible. For the given eye movement data as test samples, we conducted a classification test among the pre-defined classes based on the differences of the log-likelihood values obtained from each HMM.
For each class of face stimulus and subject, we estimated the HMM parameters from the training samples of the eye movement. We also tracked their eye movements and recorded as temporal chains their eye fixation points using an eye-tracking system. We obtained a quantitative hit rate score for each stimulus and subject. With these visual stimuli, we conducted a simple face recognition experiment, and subjects judged whether they had seen the faces before. We used a set of computer-generated faces that included both the images of actual faces and synthetic images obtained by slightly transforming the impressions of the original faces. We formulated the statistical nature of their eye movements from a machine-learning perspective by applying a hidden Markov model (HMM). We investigated the relationship between the face recognition performance of individuals and their eye movement characteristics that were measured while each subject observed the faces that were displayed on a screen.
