Description: This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet.
For eg:-wavelets can be haar, db1, db2,dmey...............
Decomposition can be viewed in figure.
(Please note that select 256X256 image for better result.)
Then compression can performed,
PERFL2 give compression score.
Then reconstruction can be performed.
Each decompsition we can choose different threshold values.
For each threshold value we can calculate mse,psnr,pq(picture quality),
bit ratio etc. To get pq install pqs function . Platform: |

Description: 基于VS2008编写，程序很简单，算法很经典实用。提出一种基于三次拉格朗日插值的自适应图像缩放算法 该算法首先计算目标像素点周围三组源像素点的方差，选取方差最小的一组源像素点，然后采用三次拉格日插值公式求得目标像素点的灰度值实验结果表明，本文算法所得的目标图像边缘清晰，且算法复杂度较低，便于硬件实现，可以实现实时图像缩放。-Based on VS2008, the program has a very simple algorithm is very classic and practical. Traditional interpolation algorithm due to the low-pass filtering effect generally makes the target image edge blur, it is difficult to obtain satisfactory visual effects in order to achieve a better quality image scaling is proposed based on cubic Lagrange interpolation algorithm for adaptive image scaling algorithm that First calculate the target pixel set of source pixels around three variance, minimum variance select a set of source pixels, then the cubic Lagrange interpolation formula obtained target pixel gray value Experimental results show that the algorithm proceeds target image sharp edges, and the algorithm complexity is low, easy hardware implementation can achieve real-time image scaling.
