First we introduce theory and merits of graphic wavelet transform, then mallat algorithm, multi - scale characteristic, quadratic b - alpine wavelet and the coefficients of this filters, and etc. later we calculate the gradient matrix based on the result of wavelet transform, thin the contour and get spatical information
先介紹圖像小波分解方法的原理、 mallat快速演算法、多尺度特性、 3階b -樣條小波基函數的選取及其濾波器系數的推導等,然後根據小波變換結果計算梯度矢量矩陣,進行非極大值抑制和雙閾值化,提取目標輪廓。In tracking section, we still adopt the snake to converge on the object contour by improving the energy functions, in the tracking frame, initial points are acquired by calculating the average inter - frame motion vector of the block, because all snaxels have approximately the same motion vector as the moving object is proposed to be rigid and have no salient deformation
跟蹤部分:根據剛體運動的特點(運動區域具有一致性和不發生較大的形變)求出運動目標的平均位移矢量,與在分割部分求出的目標的輪廓點的位置相加,作為下一幀跟蹤的初始輪廓點,結合改進的snake能量函數使其更精確地收斂到運動目標輪廓上,達到準確跟蹤的效果。
