Adaptive Image Compressive Sensing Using Texture Contrast

Figure 5

Comparison of visual qualities of 512 × 512 Lenna sampled by different methods when the sampling rate is 0.3.

(a) Original image

(b) Nonadaptive method (PSNR = 29.61 dB)

(c) Block-variance oriented method (PSNR = 32.12 dB)

(d) Edge oriented method (PSNR = 32.41 dB)

(e) Texture oriented method (PSNR = 33.56 dB)
