  1. Colour filter glass test methods temperatrue coefficient of sharp cut wavelength

    濾光玻璃測試方法截止波長溫度系數
  2. In the traditional wavelet transform, because the wavelet filter and coefficient is fixed, as a result, when the discontinuous signal is analyzed, it will produce a lot of big wavelet coefficients in the transition, which makes against the compression. in the image processing, some image is roughness, and it may has sharp edges and oddity parts

    由於傳統小波變換的濾波器長度和系數是固定不變的，不能適應輸入信號而變化，這使得在分析非連續信號時，在躍變點兩側會產生大的小波系數;對具有尖銳邊緣、分段光滑或奇異點、圖文混合圖像處理效果很差。
  3. Though avoiding noise disturbance, this method will lose some weak edge. so we take adaptive filter to sharp image edge in order to avoid losing image weak edge

    採用自適應平滑濾波銳化圖像邊緣，再進行小波邊緣檢測演算法，提出改進的基於b樣條小波變換的邊緣檢測演算法。
  4. The main work of the system can be divided into four main parts as the following : ( 1 ) 10. 5ghz bandpass filter the main contradiction of filter is caused by its function of dividing frequencies. in order to properly divide frequencies, not only need passband ’ s attenuation to be as small as possible and stopbands ’ as big as possible, but also need a sharp and quick change between the attenuation of passband and stopband, thus to make their diversity obvious

    這四個功能模塊分別是: （一） 10 . 5ghz帶通濾波器濾波器的主要矛盾是由它分隔頻率的功能決定的，為了使分隔理想，一方面要求通帶的衰減盡可能小，阻帶衰減盡可能大，亦即通帶和阻帶的衰減差值要盡量大;另一方面要求通帶和阻帶之間衰減的變化應盡可能快，最好是陡峭的跳變，使阻帶和通帶的分隔十分明顯。
  5. In order to enhance image quality, the article disposal a method by using method of color - gray transform, median filter and sharp image enhance

    針對鍋爐火焰圖像在傳輸、成像過程中的特性，本文對採集到的火焰圖像做了色彩變換、中值濾波、銳化增強、偽彩色編碼等預處理工作。
  6. Standard practice for determining the activation spectrum of a material wavelength sensitivity to an exposure source using the sharp cut - on filter or spectrographic technique

    用銳截止-打開濾波器或光譜方法測定材料激活光譜
  7. By means of mallat " s multiscale analysis, we construct two type of arbitrary order cardinal b - spline wavelet. in order to avoid the loss of weak edge, take adaptive filter to sharp image edge. this is the improved image edge detection based on wavelet transform

    本文以基於小波變換的邊緣檢測技術為基礎，在小波多分辨分析的框架下構造基於邊緣檢測的兩類b樣條單正交小波基函數，並改進現有的基於小波變換的邊緣檢測演算法。
