很多资源都说光流算法有两种类型.卢卡斯 - 卡纳德是一种稀疏的技术,但我找不到稀疏和密集的含义？有人可以告诉我密集和稀疏光流之间的区别是什么？

我正在尝试生成pdf,但我不知道如何在每个页面中添加页眉和页脚.我正在使用xsl-fo命名空间,这里是xsl代码的根.

  <xsl:template match="ROOT">
        <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
              <fo:layout-master-set>
                    <fo:simple-page-master master-name="simpleA4"
                          page-height="450mm" page-width="350mm" margin-top="20mm"
                          margin-bottom="20mm" margin-left="20mm" margin-right="20mm">
                          <fo:region-body border="solid thick black" />
                    </fo:simple-page-master>
                    <fo:page-sequence-master master-name="SequenceMaster1">
                          <fo:repeatable-page-master-reference
                                maximum-repeats="3" master-reference="simpleA4" />
                    </fo:page-sequence-master>
              </fo:layout-master-set>
              <xsl:apply-templates />
        </fo:root>
  </xsl:template>

和我的页面模板:

  <xsl:template match="PAGE">
        <fo:page-sequence master-reference="SequenceMaster1"
              text-align="center">
              <fo:flow flow-name="xsl-region-body">
                    <fo:block font-family="Arial" text-align="left"
                          language="tr">
                          <!-- ======================================Common Bigger table========================================================================================= -->
                          <fo:table width="100%" border-before-width="thin"
                                border-top-width="thick">
                                <fo:table-column column-width="310mm" />
                                <fo:table-body break-after="page" border-width="1mm" border-style="solid" height="410mm">
                                      <fo:table-row>
                                            <fo:table-cell padding-left="2mm" height="410mm">
                                                  <xsl:apply-templates />
                                            </fo:table-cell>
                                      </fo:table-row>
                                </fo:table-body>
                          </fo:table>
                    </fo:block>
              </fo:flow>
        </fo:page-sequence>
  </xsl:template>
