RBeci Posted April 25, 2023 Share Posted April 25, 2023 I tried this instruction video: But It didn't work at me What am I messing up? Thanks: Beci Quote Link to comment Share on other sites More sharing options...
firstdefence Posted April 25, 2023 Share Posted April 25, 2023 Try using a bigger brush size, go for twice the size you have in your video. Also try increasing the brush hardness to about 40% Quote iMac 27" 2019 Somona 14.4.1, iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

RBeci Posted April 25, 2023 Author Share Posted April 25, 2023 Dear @firstdefence, There is no any effect on any settings. It seems it simple doesn't work Quote Link to comment Share on other sites More sharing options...
walt.farrell Posted April 25, 2023 Share Posted April 25, 2023 Your video shows at least one effect of a known bug: the transparent preview. https://forum.affinity.serif.com/index.php?/search/&tags=AFP-2634 But supposedly that is just an error in the preview, not in the action of the brush itself. However, in a quick test in 2.0.4 the Median Brush Tool diAdn't have any effect for me, either. (Confirmed by duplicating the pixel layer, using Median Brush Tool on upper layer, and setting that layer to Difference Blend Mode.) Tried with Hardware Acceleration on, and off. Also doesn't seem to work in 2.1.0.1769 (but only tried with Hardware Acceleration on).

walt.farrell Posted April 25, 2023 Share Posted April 25, 2023 It feels like a bug, to me.

firstdefence Posted April 25, 2023 Share Posted April 25, 2023 Probably windows based because the brush works on mac OS X Monterey 12.6.4 The brush works but I do have the transparency issue.

firstdefence Posted April 26, 2023 Share Posted April 26, 2023 Topaz Gigapixel Ai has a good jpeg artefact cleanup, it can be a bit excessive, see the first image using the very compressed setting and it borders on an almost vector style but the low res setting (second image) does a good job of retaining the photo look but removing the artefacts.

RBeci Posted April 26, 2023 Author Share Posted April 26, 2023 Dear @G13RL, Could you be so kind to attach a video about the process I dont know where I am wrong. Thanks in advance if it is possible! Quote Link to comment Share on other sites More sharing options...
Staff NathanC Posted April 26, 2023 Staff Share Posted April 26, 2023 Hi @RBeci, There is a logged issue with the developers affecting both Mac and Windows which may be in part causing the issue: The Blur, Sharpen and Median brushes have no progressive effect when used on the same area of the image on a single passage (I.E if you use the brush in the same area of the image in a single pass multiple times without letting go of your mouse click, nothing further happens to that area), But if you brush over the same area with multiple passes/clicks this should still work progressively. I set up my brush settings as shown in your earlier recording and grabbed your original image and was able to remove the noise after a few brush passes, does it make any difference if you turn off Hardware Acceleration (Under Edit > Preferences > Performance) and then restart the app and try this again? Also, are you using a basic round brush from the brushes panel for this? Quote Link to comment Share on other sites More sharing options...
G13RL Posted April 26, 2023 Share Posted April 26, 2023 @RBeci, Here is the requested video. As @NathanC says, I noticed that the tool works better using individual clicks instead of dragging it across the drawing. RBeci 1 Quote Link to comment Share on other sites More sharing options...

firstdefence Posted April 26, 2023 Share Posted April 26, 2023 There is a Plugin that is compatible with Affinity called Akvis Artefact Remover: https://akvis.com/en/download.php and while it doesn't always remove all of the artefacting it can certainly speed up the process and help make the tedious removal, less so. It's also free ,although an email registration is required to get a licence key.

cgidesign Posted April 28, 2023 Share Posted April 28, 2023 (edited) Beside using APhoto's tools or other commercial products there is also the "free A.I. route" E.g., I needed a flexible upscale and artifact removal solution and found out about a database with numerous A.I. models that offer that: https://upscale.wiki/wiki/Model_Database This website lists the models and also has links to UIs to use the models (you don't need to use a command line or write your own code) Example: https://github.com/n00mkrad/cupscale This UI lets you chose which A.I. model to use (e.g. jpg fixing ones, upscalers) or even create comparisons for various different models. I selected the model: 1x_Saiyajin_DeJPEG_300000_G.pth and 2.8 sec. later I had the below result: It is not perfect, but in total the time invested was below one minute to get it. Side note: It takes a little investigation to understand the requirements to run those A.I. solutions (e.g. most of them require an installed python environment and often they prefer or need an nvidia GPU with enough vram (some even need the the nvidia cuda framework to utilize the tensor cores of the GPU); others work well on AMD cards or even the CPU (the latter one is often not recommended because it is to slow). It can be a bit confusing at first, but once it is set up, you have a lot of A.I. options for free.
