中文摘要 | 本論文提出一個針對高階視訊編碼器掃描機制的改良,使得其編碼效果 達到最佳。在 H.264/AVC (Advanced Video Coding)視訊編碼標準中,所採用的 熵編碼(entropy coding)方式,是所謂的以前文為基礎的適應性可變長度編碼 (CAVLC)。每一個圖形方塊在執行熵編碼之前,都必須事先將二維的方塊資 料掃描成一維的資料,然後依序執行熵編碼。掃描的次序改變,會影響熵編 碼的效果。H.264/AVC 所採用的掃描方式是鋸齒式掃描(zig-zag scan),這種掃 描方式對於 DCT 轉換後的係數有不錯的效果。然而,H.264/AVC 的畫面內編 碼法(intra coding)有九種不同的畫面內預測模式,不同的畫面內預測模式採用 其最適合的掃描方式,以符合不同模式的資料特性。透過實驗證明,我們提 出的掃描機制優於 H.264/AVC 視訊編碼標準所制定的方法。 |
英文摘要 | External appearance of products can transmit product image that can further evoke customer’sinternalsympathy and consuming motive. Product image play a critical role on the consumers’preference and choice of products. Besides, consumers’choice of product almost relies on their perception on product image. Therefore, it now becomes an impressing mission of product designers how to elicit consumers’affective requirements and the association with product form elements. This study is proposed to effectively map product image onto form elements and develop optimal form design and combinations. A case study of personal digital assistant is used to validate the proposed mapping procedure. The representative experimental samples and kansei word pairs were identified. The form elements and corresponding categories were also decomposed using morphological analysis method. Then a kansei experiment was conducted to measuresubject’simageperceptiondegreeofeachsample.TheQuantification Theory TypeⅠis used to analyze the relationship between form element and product image and thus establish kansei design model. A paired-samples T test procedure was proceeded to verify the reliability of the resulting model. The test results show that the difference between prediction and practical values is not significant. Therefore the model is feasible to define form design principles to assist designers to combine specified category of design elements to create specified product image. Thus, the satisfactory degree of customers preferring a certain image perception can be enhanced. |
