Coupling a model of human thermoregulation with computational fluid dynamics for predicting humanenvironment interaction

In many applications of computer graphics and design, robotics and computer vision, there is always a need to predict where human looks in the scene. However this is still a challenging task that how human visual system certainly works. A number of computational models have been designed using different approaches to estimate the human visual system. Most of these models have been tested on images and performance is calculated on this basis. A benchmark is made using images to see the immediate comparison between the models. Apart from that there is no benchmark on videos, to alleviate this problem we have a created a benchmark of six computational models implemented on 12 videos which have been viewed by 15 observers in a free viewing task. Further a weighted theory (both manual and automatic) is designed and implemented on videos using these six models which improved Area under the ROC. We have found that Graph Based Visual Saliency (GBVS) and Random Centre Surround Models have outperformed the other models.

e method of single image-based dehazing is addressed in the last two decades due to its extreme variating properties in different environments. Different factors make the image dehazing process cumbersome like unbalanced airlight, contrast, and darkness in hazy images. Many estimating and learning-based techniques are used to dehaze the images to overcome the aforementioned problems that suffer from halo artifacts and weak edges. e proposed technique can preserve better edges and illumination and retain the original color of the image. Dark channel prior (DCP) and probability-weighted moments (PWMs) are applied on each channel of an image to suppress the hazy regions and enhance the true edges. PWM is very effective as it suppresses low variations present in images that are affected by the haze. We have proposed a method in this article that performs well as compared to stateof-the-art image dehazing techniques in various conditions which include illumination changes, contrast variation, and preserving edges without producing halo effects within the image. e qualitative and quantitative analysis carried on standard image databases proves its robustness in terms of the standard performance evaluation metrics.
