代码说明:

  La transformée en ondelette discrète (en anglais Discrete Wavelet Transform, ou DWT) est une technique utilisée dans la compression de données numériques avec ou sans perte (JPEG2000). La compression est réalisée par approximations successives de l information initiale du plus grossier au plus fin. On réduit alors la taille de l information en choisissant un niveau de détail.

  • Connected-Component-based-text-region-extraction
    The basic steps of the connected-component text extraction algorithm are given below, and diagrammed in Figure 10. The details are discussed in the following sections. 1. Convert the input image to YUV color space. The luminance(Y) value is used for further processing. The output is a gray image. 2. Convert the gray image to an edge image. 3. Compute the horizontal and vertical projection profiles of candidate text regions using a histogram with an appropriate threshold value. 4. Use geometric properties of text such as width to height ratio of characters to eliminate possible non-text regions. 5. Binarize the edge image enhancing only the text regions against a plain black background. 6. Create the Gap Image (as explained in the next section) using the gap-filling process and use this as a reference to further eliminate non-text regions the output.
