Full textOver the past decade, data providers have been generating and streaming a large amount of data, including images, videos, audio, etc. In this thesis, we will be focusing on processing images since they are the most commonly shared between the users on the global inter-network. In particular, treating images containing faces has received great attention due to its numerous applications, such as entertainment and social media apps. However, several challenges could arise during the processing and transmission phase: firstly, the enormous number of images shared and produced at a rapid pace requires a significant amount of time to be processed and delivered; secondly, images are subject to a wide range of distortions during the processing, transmission, or combination of many factors that could damage the images’content. Two main contributions are developed. First, we introduce a Full-Reference Image Quality Assessment Framework in Real-Time, capable of:1) preserving the images’content by ensuring that some useful visual information can still be extracted from the output, and 2) providing a way to process the images in real-time in order to cope with the huge amount of images that are being received at a rapid pace. The framework described here is limited to processing those images that have access to their reference version (a.k.a Full-Reference). Secondly, we present a No-Reference Image Quality Assessment Framework in Real-Time. It has the following abilities: a) assessing the distorted image without having its distortion-free image, b) preserving the most useful visual information in the images before publishing, and c) processing the images in real-time, even though the No-Reference image quality assessment models are considered very complex. Our framework offers several advantages over the existing approaches, in particular: i. it locates the distortion in an image in order to directly assess the distorted parts instead of processing the whole image, ii. it has an acceptable trade-off between quality prediction accuracy and execution latency, andiii. it could be used in several applications, especially these that work in real-time. The architecture of each framework is presented in the chapters while detailing the modules and components of the framework. Then, a number of simulations are made to show the effectiveness of our approaches to solve our challenges in relation to the existing approaches

Full textIn this thesis, the main contributions are to study 2 main aspects of image quality including image aesthetic, image naturalness and the relations between the 2 concepts. More specifically, image aesthetic is the measure of how aesthetically a photo fulfills the observer’s expectation while the image naturalness definition is both related to artifacts induced by some image processing algorithms and to the individual feeling about how a picture matches with image memory. On the side of image aesthetic, the thesis deals with the problem of evaluating the roles of pre-processing operations in image aesthetic assessment. Image aesthetic assessment models based on prior image segmentation (region of interest extraction) and prior image classification (large field / close-up image classification) have been developed and compared with image aesthetic assessment models without pre-processing stages. At the same time different models base either on handcrafted features or learned features have been studied for the purpose of image aesthetic estimation. Based on the obtained results, an image aesthetic assessment model based on image classification and region segmentation has been introduced and evaluated. On the side of image naturalness, image naturalness of standard dynamic range images, especially tone-mapped images have been studied with both subjective and objective methodologies. A subjective experiment has been organized to collect human evaluations about image naturalness first. Then, various objective algorithms have been validated on the collected subjective data for the image naturalness assessment task. This work focuses on the problem of developing a model firstly to estimate if an image looks natural or not to humans and the second purpose is to try to understand how the unnaturalness feeling is induced by a photo: "Are there specific unnaturalness clues or is unnaturalness a general feeling when looking at a photo?". Finally, the relations between the 2 aspects: image aesthetic and image naturalness have been evaluated and discussed

Full textThe goal of this thesis is to add some tools in order to upgrade image quality when scanning with book digitization.First Chapter talks about image scanner whitout lighting control. This problem focuses to document camera. The goal is to correct lighting. We will see some corrections and we will suggest our method. For this part, we detect pixel's background document and we will rebuild the background of the image by them. With this information, we can correct lighting.Second chapter presents some way to do quality control after digitization, specially out of focus problem. We will enumerate different point of view to analyse and to estimate this information. To validate descriptors, we suggest to blur any picture and to compute blur estimation in order to evaluate precision. After that, we propose to combinate descriptors by machine learning.Third chapter mentions color management problem. Every image devices need to be calibrated. This chapter will expose how to calibrate scanner and explain it. We will see that L*a*b* color space is the connection profil space. To calibrate color, we must transform scanner color space to L*a*b*. We will see, in order to convert information, solution depends color chart used but we show a link between the function and thenumber of patch

Full textTraditional photo-realistic rendering requires intensive manual and computational effort to create scenes and render realistic images. Thus, creation of content for high quality digital imagery has been limited to experts and highly realistic rendering still requires significant computational time. Image-Based Rendering (IBR) is an alternative which has the potential of making high-quality content creation and rendering applications accessible to casual users, since they can generate high quality photo-realistic imagery without the limitations mentioned above. We identified three important shortcomings of current IBR methods: First, each algorithm has different strengths and weaknesses, depending on 3D reconstruction quality and scene content and often no single algorithm offers the best image quality everywhere in the image. Second, such algorithms present strong artifacts when rendering partially reconstructed objects or missing objects. Third, most methods still result in significant visual artifacts in image regions where reconstruction is poor. Overall, this thesis addresses significant shortcomings of IBR for both speed and image quality, offering novel and effective solutions based on selective rendering, learning-based model substitution and depth error prediction and correction

Full textThe objective of this investigation was to study the combined effects of supervised intermittent aerobic training, muscle strength training with electrostimulation and a continuous home-walking program, on cardiorespiratory fitness, muscle function and quality of life of patients with breast cancer during adjuvant chemotherapy period. Measurements were performed before and after 6 weeks of training on a trained group (n = 20), and 6 weeks apart without any change in physical activity on a control group (n = 12). Compared to controls, the first study showed the positive effects of our training protocol on the aerobic fitness and metabolic needs of our trained patients. Similarly, the second study revealed significant increases in MViC, ET in an isometric test, and muscle deoxygenating ΔHHb, suggesting an improvement in the use of oxygen in the muscle in the trained group after Six weeks of training. In addition, the results of the third study confirmed the effects on muscular function by observing an improvement in the myoelectric activity of the Vastus lateralis, characterized by the decrease of the RMS and the increase of the MPF during the holding phase of 50% of the MViC, in the trained group after the six weeks combined aerobic training and muscle strengthening. Finally, in the fourth study, we observed a significant improvement in the quality of life of the trained group. This improvement is characterized, on the one hand, by an increase in the overall quality of life and scores at the functional scales, and on the other hand by a reduction in the scores of symptom scales in cancer patients treated with adjuvant chemotherapy
