Photo manager addition using ML!

A few years ago i wrote a photo manager .. again .. ( see post about my first previous photo manager )
It is a web gui to find photos in my huge photo archive.
I manually added 190k tags to 120k photos in 20+ years.

I thought wouldn’t it be nice if i can generate additional metadata using Machine Learning. A few years ago i did some testing and followed a podcast and free course about machine learning.

So today i started to implement a addition to my gui. Machine recognition tags!

It already kinda works.

Things to do :

  • Make it a background job, my fileserver doesn’t run Tensorflow on a GPU, so it is slooow
  • Embed in existing GUI and stats
  • Design a editor to remove wrong tags

Below a part of ML images

Command to get a thumbnail sheet with only directory names:

montage -verbose -units PixelsPerInch -density 300 -tile 7x6 -label "%d" -font Arial -pointsize 6 -background "#FFFFFF" -fill "black" -define jpeg:size=253x154 -geometry 253x154+2+2 -auto-orient */*.JPG -title "ML Thumbs" thumbsheet.jpg

Maybe, i can use debug output like below.

['lakeside, lakeshore (score = 0.47934)', 'seashore, coast, seacoast, sea-coast (score = 0.11385)', 'sandbar, sand bar (score = 0.08822)', 'breakwater, groin, groyne, mole, bulwark, seawall, jetty (score = 0.06281)', 'valley, vale (score = 0.01790)', '']

FFmpeg tricks

Mp4 to gif (resize, cut and convert)

startsecond=0
duration=3
ffmpeg -ss $startsecond -t $duration -i 'input.mp4' -vf "fps=10,scale=320:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 output.gif

Gif to MP4

ffmpeg -i kanban.gif -movflags faststart -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" gifkanban.mp4

Converting MP4 for Davinci MOV

ffmpeg -i input.mp4 -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a pcm_s16le -f mov output.mov

And back from Davinci to MP4

ffmpeg -i render.mov -c:v libx264 -pix_fmt yuv420p -crf 16 -force_key_frames 'expr:gte(t,n_forced/2)' -bf 2 -vf yadif -use_editlist 0 -movflags +faststart -c:a aac -q:a 1 -ac 2 -ar 48000 -f mp4 out.mp4

QTVR to png (note number of frames)

ffmpeg -i ../test.mov %02d.png
ffmpeg -i %02d.png -vf "tile=1x24,transpose=1" mh.png

Nikon MOV to mp4 (no reencoding)

ffmpeg -i input.mov -c copy -movflags +faststart  output.mp4

Nikon MOV to mp4 (problems with audio?
“Could not find tag for codec pcm_s16le in stream #1, codec not currently supported in container”

ffmpeg -i input.mov -c copy -c:a aac -b:a 128k -movflags +faststart  output.mp4
Maybe add -strict experimental

MPG to MP4 (Not happy with this one)

ffmpeg -i vhs-rip.mpg"  -c:v libx264 -crf 10 -strict -2 1993-luv.mp4

FLV to MP4

ffmpeg -i filename.flv -c:v libx264 -crf 19 -strict experimental filename.mp4

Lossless cut with ffmpeg

ffmpeg  -ss 00:$2 -t 00:$3 -i $1 -vcodec copy -an cut_$1  
# an = no sound
# use -acodec copy for same codec as original audio

Timelapse JPG to MP4

ffmpeg -f image2 -r 24 -start_number 8296 -i "750_%04d.JPG"  -vcodec libx264 -profile:v high444 -refs 16 -crf 0 -preset ultrafast -vf scale=1920:1080 b.mp4

png to gif from a list

#cat png.list
file off.png
duration 1
file 20.png
duration 1
file 40.png
duration 1
file 60.png
duration 1
file 80.png
duration 1
file 90.png
duration 1
file 100.png
duration 1

# ffmpeg -f concat -i png.list -loop 0 hexlight.gif

Rotate mp4 clockwise/anticlockwise

ffmpeg -i VID20230110132531.mp4 -filter:v transpose=2 -c:v libx264 -preset veryfast -crf 22 -c:a copy -metadata:s:v rotate="" test.mp4

Concat video together

ffmpeg -f concat -i inputs.txt -c copy merge.mp4
inputs.txt
file start.mp4
file end.mp4

Error “width/height not divisible by 2 (1301×933)”

ffmpeg -i input.mp4 -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" output.mp4

Dvd/DV/Mpg etcetera overviews

I made two scripts, which take a movie, find out its lenght divide by 9. And generates a image montage of snapshots at certain times in the movie. ( A movie of 90 minutes, gets a snapshot every 10 minutes )

Example of snapshots of a movie

Below takes images as above and convert them into animated gifs. All movies in a path or directory structure gets a index page containing all animated gifs.

Example of generated directory index

I’ll post something about my media sorter also.

Ipcam sphere panorama

I made a little script to make a 360 spherical panorama photo, using a remote controlled IP cam,

Looking at the API CGI, i only needed to control the movement of the camera and getting a snapshot.

  • Point camera down
  • Point camera maximal left
  • Take picture
  • Point a little to the right
  • Take picture, loop until max right
  • Point a little more up and go max left
  • Doing same loop as above, until pointing maximal up
Made a little animation in blender

After getting all those pictures, i only needed to stitch them using Hugin.
When viewing the image with VR Glasses, i could look around my room, without image distortion, like below flattend example.

The ipcam generates a token, which you have to use in your curl commands.

TOKEN PART

token=$( curl -s -d  '[{"cmd":"Login","action":0,"param":{"rs": "abcd", "User":{"userName":"admin","password":"SECRETPASSWORD"}}}]'  "http://camera.ip.number.here/cgi-bin/api.cgi?cmd=Login&token=null"  -H 'Content-Type: application/json' | grep name | cut -f4 -d\" )

  • Cursor pad on the left
  • 1 till 5 (see below)
  • star + 1-5, rates 1 till 5 stars
  • outline star – removes rating
  • bookmark + 1-5, color marks image
  • Triangle – start slideshow
  • zoom-in, rotate CCW, reset zoom, rotate CW, zoom-out
  • previous image, open image, fullscreen, exit fullscreen to manager and next image

Wacom tablet doesn’t behave

Changed some code controlling my wacom drawing tablet.
I use this one to draw Art, diagrams and touch up photo’s.

When using multiple screens, i had the problem it would stretch the draw area over multiple screens, streching the ratio. Or it took the work screen to work on.

#!/bin/bash
# using xinput here, check post about two mouses/keyboards on one machine

# Use xrandr to check names check 
MONITOR="DP-1"
PAD_NAME='Wacom BambooFun 6x8 Pad pad'

#undo
xsetwacom --set "$PAD_NAME" Button 1 "key +ctrl +z -z -ctrl" 
xsetwacom --set "$PAD_NAME" Button 2 "key e"
xsetwacom --set "$PAD_NAME" Button 3 "key h"

ID_STYLUS=`xinput | grep "Pen stylus" | cut -f 2 | cut -c 4-5`
xinput map-to-output $ID_STYLUS $MONITOR
ID_STYLUS_2=`xinput | grep "Pen eraser" | cut -f 2 | cut -c 4-5`
xinput map-to-output $ID_STYLUS_2 $MONITOR

exit 0

Most of the times i use Krita and Gimp.

3D printed a stone

Why? Because i can

While on holiday in New Zealand i made photos of a rock i found on the campsite we where. Nothing special about the rock, but it was a nice subject to try to replicate.

So i took many many pictures of the stone from all sides.

Imported those images in meshroom and convered it to a 3D stl object.

Blender object

Printing and airbrushing

Added some grass from our clock project

Mount Taranaki New Zealand

While traveling New Zealand we went to see Mt Taranaki

Mount Taranaki (Māori: Taranaki Maunga), also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand’s North Island. It is the second highest point in the North Island, after Mount Ruapehu.

I made this timelapse using a Nikon D750.

Convert a series of jpgs into a mp4

Working on 8mm film projectors

I’ve got some old 8mm film from my father. And i wanted to digitise them.
Luckily he had some projectors. One was his own and a borrowed one.
Don’t know about the third one.

Not being used for 30+ years, none of them worked.

So i took them apart and tried to fix them.

Most of them had a driving belt issue, and two of them needed a new bulb.

In the end I had three working projectors. Let the digitising begin!

I started off with putting a Nikon camera beside it and selecting 24 frames/second and putting the speed dial just right .. i got a decent recording.

Tips:

Most drive belts still can be bought, sometimes you have to search for an alternative with same dimensions.

Measure the resistance of the power connector. The old transformers could have a shorted connection. (cause: dried out insulation of copper wires)

Use a pressurized can of air to clean the insides.

Keep track of the parts when disassembling. Those things are not made to be easy fixed.

Below a uncut/unaltered recording, so the media needs some cropping!
I love the authentic shutter sound!
