ssdkeras package - Under Construction, use at your own risk =========================================================== This is a R port to [Pierluigi Ferrari's Python implementation](https://github.com/pierluigiferrari/ssd_keras) of Single Shot Multibox Detector - [SSD](https://arxiv.org/abs/1512.02325). See how to use it for detecting eyes, nose and mouth on the [LFW faces dataset](http://vis-www.cs.umass.edu/lfw/) in [this](http://giorasimchoni.com/2017/12/04/2017-12-04-snap-fu/) blog post. Or get the gist with `train_ssd7_faces.R` with the data zipped at `lfw_faces_tagged.zip`. You should get quite good results, e.g.:  As said this is under construction though working at large. Only lightly tested on my Windows machine in which for example Python, Keras, Tensorflow are already installed. Other packages needed: `tidyverse`, `stringr`, `reticulate`, `magick` See `sessionInfo()`: ``` r sessionInfo() ``` ## Warning in readLines("~/sessionInfo_04122017.txt"): incomplete final line ## found on '~/sessionInfo_04122017.txt' ## R version 3.4.1 (2017-06-30) ## Platform: x86_***-w***-mingw32/x*** (***-bit) ## Running under: Windows 7 x*** (build 7601) Service Pack 1 ## ## Matrix products: default ## ## locale: ## [1] LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 ## [3] LC_MONETARY=English_United States.1252 LC_NUMERIC=C ## [5] LC_TIME=English_United States.1252 ## ## attached base packages: ## [1] stats graphics grDevices utils datasets methods base ## ## other attached packages: ## [1] bindrcpp_0.2 dplyr_0.7.2 purrr_0.2.3 readr_1.1.1 tidyr_0.6.3 tibble_1.3.3 ## [7] ggplot2_2.2.1 tidyverse_1.1.1 magick_1.5 stringr_1.2.0 keras_2.0.9.9000 ## ## loaded via a namespace (and not attached): ## [1] reticulate_1.3 reshape2_1.4.2 haven_1.1.0 lattice_0.20-35 colorspace_1.3-2 ## [6] yaml_2.1.14 base***enc_0.1-3 rlang_0.1.1 foreign_0.8-69 glue_1.1.1 ## [11] modelr_0.1.1 readxl_1.0.0 jpeg_0.1-8 bindr_0.1 plyr_1.8.4 ## [16] tensorflow_1.4.1.9000 munsell_0.4.3 gtable_0.2.0 cellranger_1.1.0 rvest_0.3.2 ## [21] psych_1.7.5 knitr_1.16 forcats_0.2.0 tfruns_1.0 parallel_3.4.1 ## [26] broom_0.4.2 Rcpp_0.12.13 scales_0.5.0 jsonlite_1.5 mnormt_1.5-5 ## [31] bmp_0.2 hms_0.3 png_0.1-7 stringi_1.1.5 animation_2.5 ## [36] grid_3.4.1 tools_3.4.1 magrittr_1.5 lazyeval_0.2.0 whisker_0.3-2 ## [41] readbitmap_0.1-4 pkgconfig_2.0.1 zeallot_0.0.6 xml2_1.1.1 lubridate_1.6.0 ## [46] imager_0.40.2 assertthat_0.2.0 httr_1.2.1 R6_2.2.2 nlme_3.1-131 ## [51] compiler_3.4.1
