Kaedah baru dicadangkan untuk mendapatkan semula jujukan imej dengan matlamat untuk meramalkan corak semula jadi yang kompleks dan berbeza-beza masa. Untuk itu, kami memperkenalkan rangka kerja yang dipanggil Ramalan Berasaskan Memori; ia menyediakan maklumat ramalan berdasarkan perkembangan temporal jujukan yang diambil lalu. Kertas kerja ini menyasarkan corak gema radar dalam imej radar cuaca, dan bertujuan untuk merealisasikan kaedah pengambilan imej yang menyokong peramal cuaca dalam meramalkan kerpasan tempatan. Untuk mencirikan corak gema radar, perwakilan berasaskan penampilan bagi corak gema, dan medan halajunya digunakan. Ciri tekstur temporal diperkenalkan untuk mewakili ciri corak tempatan termasuk gerakan kompleks tidak tegar. Tambahan pula, perkembangan temporal suatu jujukan diwakili sebagai laluan dalam ruang eigen bagi ciri imej, dan jarak ternormal antara dua jujukan dalam ruang eigen dicadangkan sebagai ukuran ketidaksamaan yang digunakan dalam mendapatkan jujukan yang serupa. Beberapa eksperimen mengesahkan prestasi baik skema pengambilan semula yang dicadangkan, dan menunjukkan kebolehramalan jujukan imej.

Abstract: A novel method is proposed to retrieve image sequences with the goal of forecasting complex and time-varying natural patterns. To that end, we introduce a framework called Memory-Based Forecasting; it provides forecast information based on the temporal development of past retrieved sequences. This paper targets the radar echo patterns in weather radar images, and aims to realize an image retrieval method that supports weather forecasters in predicting local precipitation. To characterize the radar echo patterns, an appearance-based representation of the echo pattern, and its velocity field are employed. Temporal texture features are introduced to represent local pattern features including non-rigid complex motion. Furthermore, the temporal development of a sequence is represented as paths in eigenspaces of the image features, and a normalized distance between two sequences in the eigenspace is proposed as a dissimilarity measure that is used in retrieving similar sequences. Several experiments confirm the good performance of the proposed retrieval scheme, and indicate the predictability of the image sequence.
