imagequality's Introduction

ImageQuality

图像质量评估工具,采用客观评估算法对图像质量进行评估。 可用于图像处理算法的验证。

目前支持的算法:

  • 峰值信噪比 PSNR (pulse signal-to-noise ratio)
  • 结构相似度 SSIM (structural similarity)

目前采用 RGB 三通道进行图像评估,不支持透明通道的计算。

用法

点击“添加”按钮会弹出“添加图像对”对话框。 添加图像暂时仅支持拖放。 点击“确认”按钮则会关闭对话框,并添加文件到主窗口。

点击主窗口左侧中任一图像对,则会在右侧显示图像质量评估算法的结果,同时也会显示所选图像对的预览图。

图像质量评估结果为延迟赋值,在第一次使用时才会计算,当图像过大时会有些许延迟。

点击“复制结果”按钮会计算图像对列表中所有图像对的图像质量评估算法的结果。 由于目前暂时未作异步处理,可能会导致主窗口无响应。 计算完成后会将结果以 CSV(comma-separated values,逗号分隔符)格式保存到剪贴板。
