Extraction and Classification of Self-consumable Sport Video Highlights

This paper aims to automatically extract and classify self-consumable sport video highlights. For this purpose, we will emphasize the benefits of using play-break sequences as the effective inputs for HMM-based classifier. HMM is used to model the stochastic pattern of high-level states during specific sport highlights which correspond to the sequence of generic audio-visual measurements extracted from raw video data. This paper uses soccer as the domain study, focusing on the extraction and classification of goal, shot and foul highlights. The experiment work which uses183 play-break sequences from 6 soccer matches will be presented to demonstrate the performance of our proposed scheme

Multi-level Semantic Analysis for Sports Video

There has been a huge increase in the utilization of video as one of the most preferred type of media due to its content richness for many significant applications including sports. To sustain an ongoing rapid growth of sports video, there is an emerging demand for a sophisticated content-based indexing system. Users recall video contents in a high-level abstraction while video is generally stored as an arbitrary sequence of audio-visual tracks. To bridge this gap, this paper will demonstrate the use of domain knowledge and characteristics to design the extraction of high-level concepts directly from audio-visual features. In particular, we propose a multi-level semantic analysis framework to optimize the sharing of domain characteristics

Event detection based on generic characteristics of field-sports

In this paper, we propose a generic framework for event detection in broadcast video of multiple different field-sports. Features indicating significant events are selected, and robust detectors built. These features are rooted in generic characteristics common to all genres of field-sports. The evidence gathered by the feature detectors is combined by means of a support vector machine, which infers the occurrence of an event based on a model generated during a training phase. The system is tested across multiple genres of field-sports including soccer, rugby, hockey and Gaelic football and the results suggest that high event retrieval and content rejection statistics are achievable

PENERAPAN OBJECT TRACKING DENGAN METODE ADAPTIVE PARTICLE FILTER UNTUK PELACAKAN BOLA PADA PERMAINAN

Data pergerakan bola dapat dimanfaatkan sebagai panduan untuk mengamati kejadian-kejadian pada pertandingan tenis yang telah berlangsung. Namun, untuk mendapatkan data pergerakan bola dari video pertandingan rentan terjadi kesalahan dalam pendeteksian objek, sehingga data yang dihasilkan terdapat noise. Berdasarkan alasan tesebut, penulis melakukan mining terhadap video pertandingan bola tenis dengan pendekatan object tracking, sehingga kesalahan deteksi ketika mendeteksi bola dapat dikurangi. Pendekatan tersebut diwujudkan dengan merancang model pelacakan bola dengan metode circle hough transform untuk mendeteksi lingkaran, kemudian dilanjutkan dengan metode pelacakan adaptive particle filter yang berfungsi untuk menghilangkan noise yang dihasilkan ketika melakukan deteksi lingkaran. Model tersebut dijalankan melalui proses-proses yang diantaranya adalah segmentasi citra, deteksi lingkaran, pelacakan objek dan diakhiri dengan koreksi lintasan. Model yang dirancang kemudian diimplementasikan pada bahasa pemrograman Phyton dan library OpenCV. Tahap terakhir dalam penelitian ini adalah melakukan eksperimen, eksperimen ini bertujuan untuk mendapatkan parameter masukan terbaik pada perangkat lunak, sehingga dapat diketahui efektifitas dari model yang telah diimplementasikan. Hasil eksperimen menunjukan bahwa video dengan jenis siaran pada lapangan hard court outdoor menghasilkan keluaran terbaik dengan rata-rata error sebesar 0,344, sedangkan hasil pengujian pada parameter lainnya harus disesuaikan dengan jenis video masukan agar mendapat error minimal.----------Ball movement data can be utilized as a guide for observing the events on the tennis matches that has lasted. However, the movement of the ball to get the data from the video game of the vulnerable object detection in error, so that the resulting data there is noise. Based on the reasons are, the author does mining against video game tennis ball with object tracking approach, so the error detection when it detects the ball can be reduced. The approach embodied by designing a model tracking ball with hough transform for circle method to detect circles, then proceed with adaptive particle filter tracking method that serves to eliminate noise generated when the detection loop. The model is run through processes such as image segmentation, object tracking, circle detection and end with correction trajectory. Model designed then implemented in the programming language Python and OpenCV library. The last stage in this research is doing experiments, this experiment aims to get the best input parameters in the software, so it can be known to the effectiveness of the model that has been implemented. Experimental results show that the type of video broadcast on an outdoor hard court field produce the best output with an average error of 0.344, whereas the test results on the other parameters must be adjusted to the type of video input so that it gets the error minimal

Video semantic content analysis framework based on ontology combined MPEG-7

The rapid increase in the available amount of video data is creating a growing demand for efficient methods for understanding and managing it at the semantic level. New multimedia standard, MPEG-7, provides the rich functionalities to enable the generation of audiovisual descriptions and is expressed solely in XML Schema which provides little support for expressing semantic knowledge. In this paper, a video semantic content analysis framework based on ontology combined MPEG-7 is presented. Domain ontology is used to define high level semantic concepts and their relations in the context of the examined domain. MPEG-7 metadata terms of audiovisual descriptions and video content analysis algorithms are expressed in this ontology to enrich video semantic analysis. OWL is used for the ontology description. Rules in Description Logic are defined to describe how low-level features and algorithms for video analysis should be applied according to different perception content. Temporal Description Logic is used to describe the semantic events, and a reasoning algorithm is proposed for events detection. The proposed framework is demonstrated in sports video domain and shows promising results

Video semantic content analysis based on ontology

The rapid increase in the available amount of video data is creating a growing demand for efficient methods for understanding and managing it at the semantic level. New multimedia standards, such as MPEG-4 and MPEG-7, provide the basic functionalities in order to manipulate and transmit objects and metadata. But importantly, most of the content of video data at a semantic level is out of the scope of the standards. In this paper, a video semantic content analysis framework based on ontology is presented. Domain ontology is used to define high level semantic concepts and their relations in the context of the examined domain. And low-level features (e.g. visual and aural) and video content analysis algorithms are integrated into the ontology to enrich video semantic analysis. OWL is used for the ontology description. Rules in Description Logic are defined to describe how features and algorithms for video analysis should be applied according to different perception content and low-level features. Temporal Description Logic is used to describe the semantic events, and a reasoning algorithm is proposed for events detection. The proposed framework is demonstrated in a soccer video domain and shows promising results
