Wavelet-based anisotropic image filter developed was also tested with the real image shown in Fig.
It is observed that the image filtered by GDGIF has the best edge preserving.

After the insertion loss in the image filter ([approximately equal to] 3 dB) and IF SAW filter ([approximately equal to] 10 dB), there is still 16 dB of gain prior to the IF amplifiers so the 5 dB noise figure of the IF amplifiers should not significantly degrade system noise figure.
Both the measured IIP3 and noise figure include the effect of an interstage SAW image filter that passes the 1930 to 1990 MHz PCS receive band.
Figure 2(d) shows another haze image with thicker haze layer, and the extracted boundary images using common guided image filter and modified guided image filter are showed in Figures 2(e) and 2(f), respectively, which are also amplified 5 times uniformly for display.
In this paper, for obtaining a smooth base layer without texture mixing, we adopt the propagated image filter which does not use the explicit spatial kernel information.
To a large extent, this ratio is determined by the first elements in the receiver line-up, that is, the insertion loss of the duplex filter, the noise added by the low noise amplifier (LNA) and mixer, the gain of the LNA and the rejection of the image filter at the image frequency.
Using a bipolar junction transistor with an incremental transconductance [g.sub.m] and a load resistance [R.sub.L] due to the image filter
[14] proposed a weighted guided image filter (WGIF) for the problem that amplification of noise in sky regions is addressed for single image haze removal.
Image Filter does not take into consideration the source of the image, not the application used to view it.
