In recent years, many hashing methods have been proposed for the cross-modal retrieval task. However, there are still some binary option robot best settings for refrigerator that need to be further explored. Although some discrete schemes have been proposed, most of them are time-consuming.
Segmenting video content into events provides semantic structures for indexing, retrieval, and summarization. Since motion cues are not available in continuous photo-streams, and annotations in lifelogging are scarce and costly, the frames are usually clustered into events by comparing the visual features between them in an unsupervised way. However, such methodologies are ineffective to deal with heterogeneous events, e. Although image-to-image translation has been widely studied, the video-to-video translation is rarely mentioned. In this paper, we propose an unified video-to-video translation framework to accom- plish different tasks, like video super-resolution, video colouriza- tion, and video segmentation, etc. A consequent question within video-to-video translation lies in the flickering appearance along with the varying frames. Multi-view learning has shown its powerful potential in many applications and achieved outstanding performances compared with the single-view based methods.
Weakly supervised temporal action detection is a Herculean task in understanding untrimmed videos, since no supervisory signal except the video-level category label is available on training data. Under the supervision of category labels, weakly supervised detectors are usually built upon classifiers. Human parsing is an important task in human-centric analysis. Despite the remarkable progress in single-human parsing, the more realistic case of multi-human parsing remains challenging in terms of the data and the model. Compared with the considerable number of available single-human parsing datasets, the datasets for multi-human parsing are very limited in number mainly due to the huge annotation effort required. Given only a few image-text pairs, humans can learn to detect semantic concepts and describe the content.
For machine learning algorithms, they usually require a lot of data to train a deep neural network to solve the problem. In practice, FPAIT has two benefits. FPAIT learns proper initial parameters for the joint image-text learner from a large number of different tasks. When a new task comes, FPAIT can use a small number of gradient steps to achieve a good performance. Translating videos into natural language sentences has drawn much attention recently.
However, the vision-language translation still remains unsolved due to the semantic gap and misalignment between video content and described semantic concept. Person re-identifcation is a key technique to match person images captured in non-overlapping camera views. Due to the sensitivity of visual features to environmental changes, semantic attributes, such as “short-hair” or “long-hair”, begin to be investigated to represent person’s appearance to improve the re-identifcation performance. Unlike previous deep learning-based methods, such as Fast-AT, which can utilize detectors introduced in object detection frameworks and generate thousands of proposals, our detector is straightforward and concise, thereby ensuring that the final cropping window is computed by its center and width, with the input aspect ratio. As attribute leaning brings mid-level semantic properties for objects, it can benefit many traditional learning problems in multimedia and computer vision communities. When facing the huge number of attributes, it is extremely challenging to automatically design a generalizable neural network for other attribute learning tasks.
Visual place recognition is challenging in the urban environment and is usually viewed as a large scale image retrieval task. The intrinsic challenges in place recognition exist that the confusing objects such as cars and trees frequently occur in the complex urban scene, and buildings with repetitive structures may cause over-counting and the burstiness problem degrading the image representations. There are threefold challenges in emotion recognition. First, it is difficult to recognize human’s emotional states only considering a single modality.
Second, it is expensive to manually annotate the emotional data. Third, emotional data often suffers from missing modalities due to unforeseeable sensor malfunction or configuration issues. Sentiment analysis on large-scale social media data is important to bridge the gaps between social media contents and real world activities including political election prediction, individual and public emotional status monitoring and analysis, and so on. Most conventional approaches mainly perform FER under laboratory controlled environment.
