We propose a method for dietary assessment to automatically identify and locate food in variety of images captured during controlled natural eating events. Two concepts are combined achieve this: set segmented objects can be partitioned into perceptually similar object classes based on global local features; used assess the accuracy image segmentation. These ideas implemented by generating multiple segmentations an select stable classifier's confidence score assigned each region. Automatic...

Modern deep learning approaches have achieved great success in many vision applications by training a model using all available task-specific data. However, there are two major obstacles making it challenging to implement for real life applications: (1) Learning new classes makes the trained quickly forget old knowledge, which is referred as catastrophic forgetting. (2) As observations of come sequentially over time, distribution may change unforeseen way, performance degrade dramatically on...

Recent work has shown a strong theoretical connection between variational autoencoders (VAEs) and the rate distortion theory. Motivated by this, we consider problem of lossy image compression from perspective generative modeling. Starting ResNet VAEs, which are originally designed for data (image) distribution modeling, redesign their latent variable model using quantization-aware posterior prior, enabling easy quantization entropy coding compression. Along with improved neural network...

Current satellite imaging technology enables shooting highresolution pictures of the ground. As any other kind digital images, overhead can also be easily forged. However, common image forensic techniques are often developed for consumer camera which strongly differ in their nature from ones (e.g., compression schemes, post-processing, sensors, etc.). Therefore, many accurate state-of-the-art algorithms bound to fail if blindly applied analysis. Development novel tools images is paramount...
