# video-color-palette-generator
Generates color palette of a given video. Using k-means for clustering the color of video frames.
This tool has two modes:
- lambdaHandler
- script
# Modes
## Lambbda
As lambda, this tool introduces two phases:
- parse lambda event request
- run `processor (script)`
### Lambda Deployment
For deployment to lambda, you'll need to build docker image
Follow steps explained here: https://docs.aws.amazon.com/AmazonECR/latest/userguide/docker-push-ecr-image.html
Then you need to create lambda function from docker image explained here: https://docs.aws.amazon.com/lambda/latest/dg/images-create.html
## Script
The output of this tool is a csv with the following structure
```
source_serial,source_url,source_duration_seconds,source_fps,sample_id,sample_number,sample_duration,palette_id,palette_counts,r,g,b,a,r_norm,g_norm,b_norm,weight
```
Data types for each attributes can be seen in this following struct
```go
type Result struct {
SourceSerial string `csv:"source_serial"`
SourceURL string `csv:"source_url"`
SourceDurationSeconds float64 `csv:"source_duration_seconds"`
SourceFPS float64 `csv:"source_fps"`
SampleID string `csv:"sample_id"`
SampleNumber int `csv:"sample_number"`
SampleDuration float64 `csv:"sample_duration"`
PaletteID string `csv:"palette_id"`
PaletteCounts int `csv:"palette_counts"`
R uint32 `csv:"r"`
G uint32 `csv:"g"`
B uint32 `csv:"b"`
A uint32 `csv:"a"`
RNorm float64 `csv:"r_norm"`
GNorm float64 `csv:"g_norm"`
BNorm float64 `csv:"b_norm"`
Weight float64 `csv:"weight"`
}
```
