摘要

Snapshot based video retrieval is the key step of efficient camera based online-offline interactions. In this paper, we propose a similar intra-shot frames merging based solution for the snapshot based video retrieval task. Firstly, the videos are compressed into SIFT feature batches by detecting and merging similar intra-shot frames. Then the min-Hash algorithm is modified to index merged features. Finally a similarity function is designed to assess the similarity between snapshot and batch, considering the ghosting effect that usually occurs in a snapshot of video. We evaluate our proposed method in an online-offline interaction advertising system. Experimental results show that our method achieves the best, performance which verifies its effectiveness in real applications.

7. Occupational therapy intervention with a child is based upon an understanding and appreciation of normal development. Knowledge of current concepts and theories related to child development is essential when occupational therapist evaluates children. This background information helps therapist to plan intervention for the child. The aim of this study is to make observation video about development of about one year old child. The purpose of my study is to help occupational therapy students learn about child development. My study is practice-based thesis. It includes product, which is the observation video and study rapport. I describe my whole process in my rapport. The process includes different kinds of stages. First, I studied those theories of child development, which are used in the studies of occupational therapy for children. These theories are Moseys Developmental Frame of Reference and the theory of development according to Sensory Integration Theory. These theories are the frames of reference of my study. I organize the child development areas according to child occupations and skills. Then I start to plan, film and edit my video based on the theories of child development and the principles of making a video. In my rapport I describe all the stages of my study and explain the sequence and the content of the stages. I also evaluate the process of my study. In the observation video you can see those stages of development where about one year old child is based on the frames of reference, which I have used in my study. I believe that my observation video can at least be good for inspiring occupational therapy students learning about child development. Keywords child development, learning, observation video [O] .
